Apprehension is best defined as:
a. goals that may not be the same, but are not mutually exclusive
b. intentionally or unintentionally using someone else's work without giving credit to the original author or creator
c. a feeling of anxiety or fear that something bad will happen
d. to meditate; ponder; think

As for this question, the best answer to this would be C. a feeling of anxiety or fear that something bad will happen.

All though D. to meditate; ponder; think comes nearer to its other meaning, it isn't as close as the correct answer. Actually, the best answer is the only correct answer. Options A. goals that may not be the same, but are not mutually exclusive, and B. intentionally or unintentionally using someone else's work without giving credit to the original author or creator, would only lead to apprehension being simulated, thus might be taken as only an example.

Try and make the question more clear : )
