Which quote from the text best supports the answer to Part A? what fear can teach us

This question is missing the options. I have found the complete question online. The options are the following:

A. "at a certain point, most of us learn to leave these kinds of visions behind and grow up. We learn that there are no monsters hiding under the bed, and not every earthquake brings buildings down." (paragraph 4)

B. "just as importantly, we need to think of ourselves as the readers of our fears, and how we choose to read our fears can have a profound effect on our lives." (paragraph 7)

C. "Terrified of cannibals, they decided to forgo the closest islands and instead embarked on the longer and much more difficult route to South America." (paragraph 9)

D. "Maybe then we'd spend less time worrying about serial killers and plane crashes, and more time concerned with the subtler and slower disasters that we face." (paragraph 11)

The quote that best supports the answer to Part A is:

B. "just as importantly, we need to think of ourselves as the readers of our fears, and how we choose to read our fears can have a profound effect on our lives." (paragraph 7)

Explanation:

"What Fear Can Teach Us" is a talk given by Karen Walker. In Part A, we must answer what the main idea of her talk is. Walker's main idea is that fears, just like storytelling, operate through our imagination. Thus, we can learn from them just like we learn from stories. Having that in mind, we can choose letter B as the quote that best supports that main idea. In this quote, Walker explains we have the ability to "read" our fears, and to choose the way to do that. Depending on the way we choose, we can affect our lives greatly.

i think the answer would mist likely be an adjective clause, because unhappy is an adjective.
