It is possible to contract h-i-v not only through sexual intercourse, but also through
a. kissing.
b. toilet seats.
c. breast milk.
d. shared drinking glasses.

Breast milk is the only answer.  HIV can be found in Breast milk although it is the lowest amount of  HIV found in bodily secretions that contain HIV.
Blood is the highest, Semen, Vaginal Secretions, and Breast milk is the order of how to low of HIV virus.

Saliva , tears, sweat, feces, and urine have not been found to have the HIV virus in them that is why all other answers are wrong.
Kissing does not transmit HIV
