Question

silicon chips are used primarily in
a integrated circuits.
b relays.
c motors.
d transformers.

Explanation:

Silicon chips are key components in integrated circuits due to silicon's semiconductor properties which allow for miniaturization and efficient electronic - signal processing. Relays use electromechanical or solid - state switching, motors convert electrical energy to mechanical energy, and transformers change voltage levels, none of which primarily use silicon chips like integrated circuits do.

Answer:

A. integrated circuits.
