I said to her, 'Will you teach me knitting?'

The correct answer is Option B (I asked her whether she would teach me knitting.).

Key Points:
• Direct to Indirect Speech conversion of Yes/No (Interrogative) questions.
• Reporting verb 'said to' changes to 'asked'.
• Yes/No questions require the connective conjunction 'whether' or 'if' (never 'that').
• In the reported clause, interrogative word order flips to assertive statement word order.
• Pronoun shift: 'you' becomes 'she'.
• Tense shift: 'will' shifts to past modal 'would'.
• Thus: 'I asked her whether she would teach me knitting.'
• Key Takeaway: In indirect reporting of Yes/No questions, use 'whether/if', change 'will' to 'would', and use assertive word order.
