Correct Answer :
A. Microwaves are the principle carriers
In this question the word principle is wrongly spelt. The letter under this part is (a), therefore, (a) is the correct answer. The correct form would be Microwaves are the principal carriers, which means microwaves are the chief or main carriers.
The word principle is not used because it means a basic general truth that is the foundation of something.
