#4
Which sexually transmitted infection (STI) is characterized by the formation of painless genital ulcers called chancres?

#7
Which sexually transmitted infection (STI) is caused by a protozoan parasite?
Trichomoniasis
ExplanationTrichomoniasis is caused by a protozoan parasite called Trichomonas vaginalis, typically transmitted through sexual contact.
#8
Which sexually transmitted infection (STI) is known as the 'silent infection' due to its often asymptomatic nature in both men and women?
