C is Incorrect the correct answer is B.

The question states that the hours of pop music in her collection is 25% more than what it was the last month so it is increasing.

The correct answer is f(x) = 5(1.25)^x + 4

This is because in the question it states that the hours of classical music (4) does not change meaning that 4 is the constant and 5 is the initial value that changes over time (P).

Hope this helps.
