Answer: Choice B is an example of strong characterization, also called direct characterization.
Explanation: Ben was always fearless. <em>No guessing</em>
He had been skydiving many times and was never scared. He bravely fought for his country without a moment’s hesitation. When his plane lost an engine he never lost his cool, and brought it down safely. <em>These descriptions of his experiences present a clear picture of the kind of person Ben is.</em>
However when he heard that his wife might be sick, he was scared. <em>New situation, clearly described, and a change in his emotion directly stated.</em>
In the other examples, there are descriptions of circumstances and conditions. The reader can infer some things about the characters who are in those situations and their emotional states.
