If the frequency to a capacitor increases, the current through it
- decreases.
- increases.
- is zero.
Explanation from PART66Online
Capacitive reactance equals 1 / (2 x pi x f x C), so it falls as frequency rises. With less reactance opposing the flow, more current passes through the capacitor at the higher frequency.

if the formula for capacitive reactance is 1/2piFC
then as frequency increases capacitive reactance would decrease
this would in turn allow more current to flow?

yes current will increase

If it really does mean 'through' it, the answer is zero, as no current goes 'through' a capacitor regardless of its frequency.
However, if it means the current in the circuit, the capacitive reactance will go down, thus its current will go UP.
