Ugh, statistics questions are the worst. I'm going to close my eyes and point to an answer. Maybe I'll get lucky with B) [1, 2].

Haha, this question is making my head spin! Linear regression is not my strong suit. I'll just go with C) [0, 3] and hope for the best.

A) [0, 1.5] seems like the correct answer to me. The confidence interval should include the true value of the coefficient, and this range looks about right.
