Step 1: Identify the verb tense in direct speech
The original sentence is in present simple negative: "don’t like''.
Step 2: Apply the rules of tense shift in reported speech
Since the reporting verb "said'' is in the past tense, we change the present simple "don’t like'' to past simple "did not like''.
Step 3: Adjust the subject pronoun
"I'' changes to "she'' to match the subject "Sheila''.
Step 4: Eliminate incorrect options
- Option A: "she do not'' is grammatically incorrect.
- Option C: Changes tense unnecessarily to present perfect.
- Option D: Changes mood to future — incorrect.
Conclusion: Option B correctly uses past simple tense and the proper subject.
