Correct option is B
The correct substitution is:
“never bothered to”.
Explanation:
“Were never bothering” is incorrect in this context, as the event seems to have occurred in the past. The action is
completed and definite, so
Simple Past — “never bothered to” is the correct form.
Grammatical Rule Used:
For
completed past actions, use
Simple Past (V2), not Past Continuous.
Explanation in Hindi:
जब कोई कार्य भूतकाल में पूरा हो गया हो, तो वहां “Past Continuous” का प्रयोग नहीं होता।
इसलिए “never bothered to” का प्रयोग उचित है।
Example:
They never bothered to call back. ✅
