Answer:

Statement B is the correct answer

Explanation:

This is because answer choices A and D are completely incorrect as neither of these things could even relatively true. Then answer choice C could be viable although there would be a lot of questions to ask before determining if this answer works in the context of the situation, therefore, since it is a contextual choice the only one left is B.

Pro Tip: In problems like this where there is no stimulus, or context included in the question, all situational answers such as answer choice "C" can be eliminated.
