Assertion (A): For high frequency lines inductive reactance is very high as compared to ac resistance.

Reason (R): Due to skin effect ac resistance of line is higher than dc resistance.

[A]. Both A and R are correct and R is correct explanation of A
[B]. Both A and R are correct but R is not correct explanation of A
[C]. A is correct but R is wrong
[D]. A is wrong but R is correct

Answer: Option B


XL = ωL. As frequency increases line resistance increases slightly but XL increases directly as per frequency.
