Answer:
I'm gonna say A) Allen considers whether to tell the truth.
Explanation:
If you havent learned the different forms of conflict. Here are the four main types. Man vs. Man, Man vs. Nature, Man vs. Self, and Man vs. Society.
For internal conflict, it would be Man vs. Man. Aka, the character Allen is struggling to themself, thinking on whether or not they should tell the truth.
Letter B would be Man vs. Nature
letter C would be Man vs. Man
and Letter D, depending on the context of the story, would either contain no conflict or would be Man vs. Society.
This is just my educated guess by the way. But I'm 90% sure the answer is A.
