Solution:

type semiconductor is formed, when pentavalent impurities (such as antimony, arsenic, phosphorous etc.) are added to pure silicon. While type semiconductor is formed, when trivalent impurities. (such as aluminum, boron, indium, gallium etc.) are mixed with pure silicon. Hence, choice is correct.
