Find the Wrong Option and Explain Why
Error-spotting questions where students must catch the incorrect statement and justify the catch.

✅ How to use this effectively
- 1. Fill class, board and chapter.
- 2. Choose how many items you want.
- 3. Send the prompt.
- 4. Print the questions for students.
- 5. Use the key to discuss each error.
🔧 If it is not right, reply with this: If two options are wrong instead of one, reply: 'Q2 has two incorrect options - make exactly one option wrong and the other three correct, then re-verify.'
THE PROMPT
ROLE: Act as a mathematics teacher who designs error-detection questions to sharpen reasoning.
CONTEXT: I teach [CLASS/GRADE] for [BOARD or EXAM e.g. CBSE / ICSE / State Board / JEE / NEET]. The chapter is [CHAPTER NAME]. I want [NUMBER, e.g. 8] 'find the wrong option' questions.
YOUR TASK:
1. For each question, write a short stem like 'Which of the following statements is INCORRECT?' followed by four statements A to D about the chapter.
2. Exactly THREE statements must be correct and exactly ONE must be wrong.
3. Make the single wrong statement reflect a common misconception, not an obvious nonsense.
4. Vary which option (A/B/C/D) is the wrong one across the set.
INPUT: Here is the sub-topic or specific misconceptions to target: [PASTE TOPIC OR LEAVE BLANK].
HOW TO WORK IT OUT: Check the truth of all four statements per question before finalising. VERIFY that exactly one is false (re-test each statement, use a counter-example for the wrong one). Do not invent rules. Keep maths legible.
OUTPUT FORMAT:
SECTION 1 - QUESTIONS: each stem with four statements A to D, no answers.
SECTION 2 - ANSWER KEY: table with Q No | Wrong option | Why it is wrong | The corrected statement.
RULES: Exactly one wrong option per question. The other three must be genuinely correct. No trivially silly options. Difficulty suited to the class above.
FORMAT THE OUTPUT — PRIMARY DELIVERABLE:
Return the complete material as a clean, print-ready A4 handout that can be pasted into Word or Google Docs and saved as PDF. Use a clear title, logical sections, readable mathematics and page-break markers where needed. Keep student material separate from the answer key or teacher notes.
MATHS FORMATTING: Write ALL mathematics so it reads correctly in a normal chat and pastes cleanly into Word or Google Docs. Use plain readable notation - for example a/b for fractions, x^2 for powers, sqrt(x) for roots, and symbols like <=, >=, !=, +-, pi, theta, integral and sum. Do NOT output raw LaTeX or code such as \frac{}{}, \sqrt{}, x^{2}, $...$ or \( ... \) - these appear as broken symbols to a teacher in a free chat.
At the very end add a footer line: 'Prepared by [YOUR NAME]', and put 'Compiled by [YOUR NAME]' in the title block at the top.
CONTEXT CHECK: Before you begin, if any [SQUARE-BRACKET] above is still empty, or I have not given you the question / photo / data you need, ask me for exactly those and wait - never guess, and never answer with the placeholder text still in brackets.
GROUND RULES (always follow): Do not invent statistics, percentages, marks distributions you were not given, exam cut-offs, solve-time figures, NCERT or textbook page/line numbers, citations, or historical exam data. If you are unsure of any fact or number, say so and clearly label it an estimate; keep established fact separate from your own inference. Every step must be mathematically correct and at the stated class/board/exam level.
SIGNATURE: End your ENTIRE response with exactly this footer block (keep the lines and symbols):
