AIDS is transmitted sexually or through blood transfusion or from mother to fetus.
Tetanus is not transmitted from person to person or from animal to person.
Hepatitis-B is transmitted through blood and infected bodily fluids.
Rabies is a fatal viral disease of mammals, most often transmitted through the bite of a rabid animal.
Therefore, the correct answer is option b.

A zoonotic disease is a disease that is transmitted from animals to humans. They can be caused by viruses, bacteria, parasites and fungi. Measles is a viral disease in humans. Diptheria is caused by bacterium Corynebacterium diptheriae. Leprosy is chronic infection caused by bacteria Mycobacterium leprae.
Rabies is one such zoonotic disease caused by the rabies virus of the genus Lyssavirus.
Thus, the correct answer is option (D), 'Rabies'.

Tuberculosis is a disease caused by the bacterium Mycobacterium tuberculosis. Influenza is caused by Haemophilus influenzae.  The infected person coughs and sneezes. These diseases are transmitted through the air droplets while sneezing and coughing. The causative agent survives in the air droplets and through the air, the disease is transmitted to the other person. 

Early symptoms of active TB can include weight loss, fever, night sweats and loss of appetite. Symptoms may be vague, however, and go unnoticed by the affected person. For some, the disease either goes into remission (halts) or becomes chronic and more debilitating with cough, chest pain and bloody sputum (saliva). 

Bacillus Calmette–Guérin (BCG) vaccine is a vaccine which is primarily used against tuberculosis. In countries where tuberculosis or leprosy is common, one dose is recommended in healthy babies as close to the time of birth as possible. In areas where tuberculosis is not common, only children at high risk are typically immunized, while suspected cases of tuberculosis are individually tested for and treated.

Tuberculosis (TB) typically presents with chronic symptoms including a persistent cough, weight loss, and an evening rise in body temperature.

BCG vaccine stands for Bacillus Calmette-Guerin. It is a vaccine against tuberculosis and for the treatment of some bladder cancers.
So, the correct answer is option A.

BCG, or Bacille Calmette-Guerin, is a vaccine for tuberculosis (TB). It is made from weakened tuberculosis bacteria that infect cows, similar to the human form of tuberculosis. The vaccine is 70-80% effective against the most severe forms of TB, such as TB meningitis in children.

Bacille Calmette-Guerin (BCG) is commonly used against tuberculosis. It is normally given to children as it has been shown to provide very good protection against the disseminated forms of TB in children, including TB meningitis. The other diseases do not have any vaccines yet.
