Reactive power requirement requires which element

Homework Statement

Homework Equations

I think it should be A for 1st and B for 2nd
Shunt capacitor is used to improve power factor by giving reactive power to line.
Series capacitor is used to improve efficiency of line as it nullifies effect of line inductance.

And for 2nd Q proportional to V²/X is the formula.

The Attempt at a Solution

Am I right or is the pasted answer in picture right?

I agree, 1 A, 2 B.

Series capacitors are seldom used, forget about them.

Utilities don't try to correct power factor, they try to keep voltage at all load busses within allowable limits. See the PF Insights article.
