I wish you don’t quarrel so much with your sister.

Correct option is B

· Original Sentence: I wish you don’t quarrel so much with your sister.
· Grammar Rule: When expressing a wish about something undesirable in the present or future, we use the construction:
“I wish + subject + wouldn’t + base verb” NOT “don’t” – because “wish” takes a subjunctive tone, not direct present tense.
· Correct Form: I wish you wouldn’t quarrel so much with your sister.
· Option Analysis:
· (a) No improvement – ❌ “don’t quarrel” is incorrect after “I wish.”
· (b) wouldn’t quarrel – ✅ Correct use of “wish” + “wouldn’t”
· (c) mustn’t quarrel – ❌ Sounds like a command, not a wish.
· (d) aren’t quarrelling – ❌ Incorrect tense and structure with “wish.”
✅ Correct Sentence: I wish you wouldn’t quarrel so much with your sister.
Therefore, the correct answer is (b) wouldn’t quarrel.
