Concept:The word "halt" means to bring something to a complete end, so we need the closest matching word from the options.

This means giving guns to the police does not completely end crime.
Check each option:
A. "avoid" means to keep away from something, not the same as halt.
B. "prevent" means to stop something before it happens, but it is not the exact meaning of halt.
C. "stop" means to bring to an end, which directly matches halt.
D. "suspend" means to pause temporarily, not to end completely.
