Answer:
Having multiple sexual partners pose the greatest risk of getting STI
Explanation:
Sexually transmitted infections are infections that are normally transferred by sexual contact with the infected person. Sexually transmitted infections can be caused by bacteria, viruses, protozoa.
So as these diseases are transferred by sexual contact than having multiple sexual partners increase the chances of getting an STI. Apart from multiple sexual partners unprotected sex is also greatly responsible for the transfer of STI from one person to another person.
STI caused by bacteria and protozoa are curable by drugs but the STI caused by the virus is not curable so multiple sexual partners and unprotected sex should be avoided.
Therefore the right answer is- having multiple sexual partners pose the greatest risk of getting STI.
