Answer:

Gallium

Explanation:

Gallium is one such element used as a do/pant in a p-type semiconductor.

For p-type conductors, they are best do/ped with elements with 3 valence electrons. These are group 3 elements. From the choices, only gallium belongs to this group.

Other elements given are good do/pants for n-type semiconductors. They have 5 valence electrons.
