Explanation:

Maggots are the larvae of flies. For maggots to appear on rotting meat, flies need to lay eggs on the meat. In a covered jar, flies cannot access the meat to lay their eggs, so no maggots develop. The other options are illogical: "They got lost" is not a scientific reason, "We don't know" is incorrect as the reason is known, and "They don't like meat" is false since maggots (fly larvae) do feed on rotting meat.

Answer:

C. Flies could not get to the meat to lay eggs
