Answer 1

Answer:

Your answer is here:-

Explanation:

To make p-type semiconductor, impurity added with pure silicon should be (a) Indium.

Hope it helps you.

Answer 2

Answer:

B

boron

D

aluminium

As silicon lies in the group 14 of the modern periodic table thus to convert a pure silicon into a p-type semiconductor, it must be doped with impurity containing atoms which lie in group 13 in modern periodic table such as boron and aluminium.
