Concept:The question tests the correct spelling and meaning of the word used for making a bomb safe.
Explanation:The sentence tells us the brave officer handled the time bomb and prevented it from exploding.
The correct word is "defused."
To defuse means to remove the fuse from a bomb or to make a dangerous situation safe.
Option A, "diffused," means to spread or scatter widely, so it is not correct here.
Option B, "druse," is not a verb used for bombs.
Option D, "difused," is simply a misspelling.
Therefore, the word that best fits the sentence is "defused."
Answer:C. defused
