Explanation:

This sounds like a homework problem.

You need to understand how frequency affects inductive reactance and a capacitive reactance. As the reactance of a device increases, its impedance increases.

A general statement is inductors offer a lower reactance to lower frequencies and a higher reactance to higher frequencies. The specific relationship between frequency and XL is expressed by this equation:

XL = 2 x pi x f x L.

You can see that XL increases as f increases.

A general statement is capacitors offer a lower reactance to higher frequencies and a higher reactance to lower frequencies. The specific relationship between frequency and XC is expressed by this equation:

XC = 1/(2 x pi x f x C).

You can see that XC decreases as f increases.

I suggest assigning values for f, L and C and calculate XL and XC. Then double the value of f, recalculate both and you will have your answer
