B. Trichomoniasis
C. Gonorrhea
D. None of these

Answer 1

Hint: Disease is described as disorder or dysfunction in the body of the organism and it produces several symptoms and pathogenic conditions. The diseases are caused by injury, malfunctioning or by pathogenic infections. Several pathogens such as the bacteria, virus and fungi are known to cause diseases in animals and humans.

Complete answer:
Sexually transmitted diseases are the diseases that are the diseases that are commonly spread through sexual activity. The sexually transmitted diseases are caused by pathogenic agents such as the bacteria, viruses and the parasites. These pathogenic agents spread through the genital parts such as vagina, anus and the penis and spread through sexual contact with the infected person.
Trichomoniasis is caused by the parasite Trichomonas vaginalis and is an infectious sexually transmitted disease. The important symptoms include itching and uneasiness in the genital parts, foul smelling vaginal discharge and pain during urination. This disease increases the risk of getting HIV or AIDS.
The bacterium Neisseria gonorrhoeae is the causative agent of gonorrhea in humans. It is a type of sexually transmitted disease and known as the clap. Infections in this disease involves genital infections, rectum and urinary infections and infection of the mouth. The infections in men include symptoms such as pain in urination, discharge from penis or testicular pain. In women, the infections may be vaginal discharge, abnormal vaginal bleeding or pelvic pain.
Chlamydiosis is an intracellular infection caused by bacterial species of Chlamydia psittaci. It causes serious lethal infections in the birds, mammals and respiratory disorders in humans. The bacteria is transmitted through inhalation, contact or ingestion and can spread through the birds to humans. The birds serve as a medium of transmission of the bacteria infection. In humans, the disease causes high fever, respiratory problems as well as pneumonia. In humans, the disease is also known as psittacosis or parrot fever.

Hence, the correct answer is option (A).

Note: Sexually transmitted diseases are caused by the pathogenic bacteria and viruses as well as due to the infection caused by parasites. These types of diseases are spread through sexual contact with the infected person and may be transferred to the fetus during pregnancy. The disease Chlamydiosis is not a sexually transmitted disease. It affects the respiratory system and causes respiratory infections.
