I've got them both for you. It was not difficult to do it. You need to pay more attention on grammar as it's very important stuff. Here are your answers:
1. I'm definitely sure that this phrase B. in the basement in the sentence given above is a perfect example of an adjective phrase. Just look the sentenceattentively, and you'll get it.
2. The same as the first task. B. of baseball cards is perfectly fits as the adjective phrase. It's 100% the same reason as the previous one.
