Full Answer
B.Sexual intercourse✓ Correct
Sexual intercourse
HIV is a virus that is transmitted through the exchange of certain bodily fluids, such as blood, semen, and vaginal fluids. Therefore, unprotected sexual intercourse is a primary mode of transmission. It can also be spread by sharing needles or from an infected mother to her baby during childbirth or breastfeeding. It is not spread through air (like coughing) or by touching surfaces.
Common mistakes
✗ Confusing HIV transmission with airborne diseases like the common cold or flu.\n✗ Thinking HIV can be spread by casual contact like touching surfaces.
