Answer: C. is less likely to be eaten by a predator.
Explanation:
The adult seven-spotted cockroach is the prey of various other insects including beetles so mimicking the pattern of a beetle would send a message that it is a beetle and because the chemical irritant that the beetle has makes it get avoided by others, the cockroach gets avoided by other insects too who don't want to be sprayed.
Of course this does not always work but it works for the most part and ensures the cockroach's survival.
