Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A), (B) and (C) only
Sexually transmitted diseases (STDs, also called sexually transmitted infections) are infections passed from one person to another mainly through sexual contact. Common examples are gonorrhoea, syphilis, genital herpes, chlamydiasis, genital warts, trichomoniasis, hepatitis B and HIV infection, which leads to AIDS.
(A) AIDS Correct. AIDS is caused by the human immunodeficiency virus (HIV), which spreads through unprotected sexual contact, transfusion of infected blood, shared needles and from an infected mother to her child.
(B) Hepatitis B Correct. The hepatitis B virus attacks the liver and spreads through blood and body fluids, including sexual contact, so it is counted among the STDs.
(C) Syphilis Correct. Syphilis is a bacterial infection, caused by Treponema pallidum, that spreads mainly through sexual contact.
(D) Psoriasis Incorrect. Psoriasis is a long-lasting skin disease with red, scaly patches, caused by the body’s own immune system; it is not an infection and does not pass from person to person.
