|Impedance(z) = R-jXc.
Xc = 1/2pifc now as frequency increases capacitive reactance(Xc) will decreases so total impedance will rise.

|Z=R-(j/fc), as f decreases, 1/fc factor increases so Z will be decreased. Correct answer is option B. Please change the option as early as possible.|

So if F decreases Xc increases. So Z=SQRT (R^2+ Xc^2) increases.

|Yes, the impedance would fall.|
