I could give you the answer to # 3, but I don't know about the other two. A capacitor is like a small battery. It charges and discharges in an electronic equipment. It could be in almost 99.9% of electric equipments. Therefore, the answer is (d). However, if by (c) they mean Consumer electronic Unit, the that could be too.
