As frequency increases, which statement about reactance is true?

Explanation:
As frequency increases, inductive reactance rises because X_L = 2πfL, so doubling the frequency doubles the opposition an inductor presents to the current. Capacitive reactance, on the other hand, is X_C = 1/(2πfC), which means it decreases as frequency grows. So the statement that inductive reactance will increase is the correct one, while capacitive reactance does not increase with frequency.
