Answer:
C. If you are not sexually abstinent, you will contract an STI, maybe even AIDS.
Explanation:
Abstinence is a term that describes a practice in which an individual deny him/herself for doing certain thing(s). In other words, it is an act of abstaining from indulging or satisfying oneself from a desire or appetite. Notably from sex or hard drugs.
Therefore, in this case, to argue in favour of Abstinence, from the options given, a reasonable argument is option C which is "If you are not sexually abstinent, you will contract an STI, maybe even AIDS."
This implies that, if an individual keeps having or indulging in sexual practices without caution, such person, will contract an STI acronym for Sexually Transmitted Infections such as Herpes, hepatitis B etc., and as well AIDS, which is often contracted through sexual intercourse.
