Which of the following diseases are sexually transmitted?

(A) AIDS

(B) Hepatitis B

(C) Syphilis

(D) Psoriasis

Choose the correct answer from the options given below:

Option 1 -> Includes AIDS, Hepatitis B, and Syphilis - all are sexually transmitted diseases, excluding Psoriasis which is not an STD.

Option 2 -> Incorrectly includes Psoriasis (a non-infectious autoimmune condition) and excludes Hepatitis B (which is sexually transmitted).

Option 3 -> Incorrectly includes Psoriasis, which is an autoimmune skin disorder, not a sexually transmitted disease.

Option 4 -> Excludes AIDS (which is sexually transmitted) and incorrectly includes Psoriasis (which is not an STD).

Hence, Option 1: (A), (B) and (C) only -> AIDS (HIV), Hepatitis B, and Syphilis are all sexually transmitted diseases that can spread through sexual contact. Psoriasis is an autoimmune skin condition with no infectious component and cannot be transmitted sexually or otherwise -> correct
