AC circuit Multiple choice question

[Jahnavi]

Homework Statement

More than one options may be correct .

Homework Equations

Inductive reactance =ωL

Capacitive reactance = 1/ωC

The Attempt at a Solution

On increasing the frequency , inductive reactance increases whereas capacitive reactance decreases . Thus , option a) is correct .

But since net reactance of the circuit also increases , option d) should also be correct .

So I think both a) and d) are correct .

But this is wrong .

Which one is greater at very low frequency? X_L or X_c?

What is the total reactance here? What happens to it when you increase the frequency 'slightly'?

Which one is greater at very low frequency? XL or Xc?

I was missing the key thing ( " at very low frequency " ) and incorrectly assuming inductive reactance to be greater than capacitive reactance .Thus getting option d) .

I need to be more attentive while reading the question .

Thank you so much
