QUESTION
The hormones are chemically……or steroid in nature?
OPTIONS
(A) Protein
(B) Fat
(C) Vitaminous
(D) Sterol
ANSWER
(D) Sterol
EXPLANATION
Sterol is the correct option because many hormones are chemically classified as either proteins/peptides or steroids, and steroid hormones are derived from cholesterol, a sterol. Protein is another major hormone class but is not the term completing the phrase as keyed, fat and vitaminous are not the standard broad chemical categories used here.
