Answer :
Final answer:
A low explosive has a velocity of detonation less than 1000 meters per second, which makes option c the correct answer.
Explanation:
A low explosive has a velocity of detonation that is less than 1000 meters per second. This distinguishes it from high explosives, which detonate at speeds greater than 1000 meters per second. The description of a low explosive falling under this threshold answers the question posed, identifying that the correct option is c. 1000 meters per second.
