Solution


Q.

Assertion: HIV/AIDS is a viral disease.
Reason: HIV infection is spread by sexual contact with an infected person.
1 Both assertion and reason are correct and reason is the correct explanation of assertion.  
2 Both assertion and reason are correct but reason is not the correct explanation of assertion.  
3 Assertion is true but Reason is false.  
4 Assertion is false but Reason is true.  

Ans.

(2)

HIV infection is caused by the human immunodeficiency virus. One can get HIV from contact with infected blood, semen, or vaginal fluids. Most people get the virus by having unprotected sex with someone who has HIV. Another common way of getting it is by sharing drug needles with someone who is infected with HIV. Thus both assertion and reason are correct but reason is not the correct explanation of assertion.
