Answer 1

The correct option is D if both Assertion and Reason are false

AIDS is a secondary immunodeficiency disease. Secondary immunodeficiency occurs in individuals in which originally normal immune system gets impaired due to prolonged illness, malnutrition, radiation and use of certain drugs. Primary immunodeficiency exists from-the birth. AIDS is transmitted only by a contact of infected cells containing blood of a patient with the blood of a healthy person. AIDS virus has been found in urine, tears, saliva, breast milk and vaginal secretions and semen. So, sexual intercourse with infected partner can transmit disease. HIV is a fragile virus and does not survive well outside the body. It is therefore considered that ordinary social contact with HlV-positive subjects involves no risk of infection. So, the correct answer is 'if both Assertion and Reason are false'.
