Answer:
B. To use facts and details to draw conclusions that are not specifically stated.
Step-by-step explanation:
There's not much of an explanation. A is easily knocked out because denotation of a word has little to nothing to do with an inference. C is easily knocked out because it doesn't matter what the literal meaning of something is. D is also knocked out because what you do know doesn't matter either. You need information the author has given you, so B.
An inference is officially defined as a conclusion reached on the basis of evidence and reasoning. So, it's B.
