Question

Which phrase accurately characterizes sexually transmitted infections (STIs)?

are caused by bacteria, viruses, or parasites
always cause visible symptoms
are rarely transmitted by sexual contact
can be contracted only by women

Answer 1

Answer:

the first one

Explanation:

i I think it's the first one because viruses usually are the cause of the infections along with bacteria and parasites and they are not always visible and are not rarely by sexual contact but instead mostly, that's why they're called sexual transmitted diseases and cannot only be contacted by women so I think that's the best answer. I'm open to correction
