Answer: Option D
Answer: (d)The last two sentences give the hint for the word which would fill the blank. ‘Extreme restraint was exercised, and opportunity was given to the militants to surrender. The four surrendered’. The highlighted sentences suggest that the militants weren’t killed or eliminated because extreme restraint was exercised, and the militants surrendered. Zap [verb] means ‘go quickly’; Spawn [verb] ‘(of a fish, frog, mollusk, crustacean, etc) release or deposit eggs; produce (offspring)’; The words ‘zapped’ and ‘spawned’ are irrelevant to the context of the sentences. It makes more sense that the surrendered militants were arrested. Hence, option (d) is the correct answer.
