Homework Answers
Choice B is correct.
Since all the above compounds are steroids hence their basic skeleton would consist of 17 carbon atoms fused together in the form of 3 six member rings and 1 five member ring , which is illustrated in the option B clearly.
option a is eliminated as none of the steroid has double bond at the position given in option a
option c is eliminated as aldosterone and THG do not mimic the structure shown in option c
option d is eliminated as cholesterol do not have ketone group as that is present in option d
