For attenuation of high frequencies we should use
Answer: Option
Explanation:
Since Xc for high frequencies is low, the high frequencies are shunted to ground and are not transmitted.

I think inductance is not the correct answer because it's not specified whether the inductance is introduced in a series or a parallel fashion, making shunt capacitance the correct answer.

Inductance because, Beacuse xl = jwl.
So increasing frequency reactance increases.
So increasing frequency reactance increases.

If frequency increases reactance decreases both in parallel and series then why only shunt capacitance?

Shunt capacitance can be said as band pass not attenuation. This way inductor can also be used.

Attenuation of high frequencies is done by Low pass filter and in low pass filter we use shunt capacitor. We generally don't use inductor because of it's bulky size and high cost.

Why not be an inductor?

High pass filter will pass the high frequency and attenuate the low frequencies, High frequency components are eliminated in LPF. In LPF the we have shunt capacitor.

For highpass filter, we have the capacitor in series and shunt resistor.
Then why don't be the series capacitor?
Then why don't be the series capacitor?

Inductor block AC[high frequency], Capacitor pass AC.

High frequency components are eliminated in LPF in it we place capacitance in shunt to the source.
