Answer:
B) Increase
Explanation:
As,
Xc=12πfC
Glass has a higher dielectric constant than air or vaccum so....
The value of a capacitor when the air dielectric is replaced by a material with a higher dielectric constant increases!
And as the brightness of a bulb depends upon the current through it, and that reducing one of the impedances in a series circuit will increase the current.
