Q1:

The primary reason for the widespread use of Si in semiconductor device technology is

A abundance of Si on the surface of earth

B larger band gap of Si in comparison to Ge

C favourable properties of Silicon-dioxide (SiO2)

D lower melting point

ANS:C - favourable properties of Silicon-dioxide (SiO2)

Here a, b, c are the reason of widespread of silicon, but the primary reason is an abundance of silicon on the surface of the earth. So option A is the answer.
