Correct option is B
The correct option to fill in the blank is (b) sparked.
Sparked means caused or set off (something sudden), fitting the idea that a remark started an argument. The past-tense form also agrees with the sentence. (Hindi:
भड़का दिया/चिंगारी लगा दी).
Example: A careless joke sparked a heated debate.
