Solution

The correct option is B MMR vaccine
A vaccine is a preparation containing inactivated antigenic proteins of a pathogen or inactivated/weakened pathogen that is introduced into the body.

The antigens in the vaccine trigger the B and T lymphocytes to produce antibodies and other cytotoxic cells that destroy the antigen. The memory B and T lymphocytes generated in response to the vaccine launch a faster and stronger immune response against the pathogen in the event of an actual infection in the future. This principle (memory) helps in the prevention of many infectious diseases.

Mumps is a viral disease caused by a Paramyxovirus which is a member of the Rubulavirus family. The virus primarily affects the parotid salivary glands, resulting in inflammation and painful swelling. The ideal way to prevent the disease is by administering the MMR vaccine which is a combination vaccine that protects against three diseases: measles, mumps, and rubella. The vaccine contains live but attenuated (reduced ability to cause the disease) forms of Mumps, Measles and Rubella virus. It is injected subcutaneously (into the fatty connective tissue below skin).

Salk vaccine or the inactivated polio vaccine (IPV) is administered to prevent the occurrence of poliomyelitis caused by the Poliovirus. The vaccine consists of killed viruses and is administered through injections in the arm or leg (intramuscular or subcutaneous).

BCG or the Bacillus Calmette-Guerin vaccine is used as a preventive measure for tuberculosis, a bacterial disease caused by Mycobacterium tuberculosis. The vaccine is a liquid preparation of a live attenuated bacteria which is placed directly onto the skin of the upper arm. It is then pricked through the skin using a multi-pronged needle device that delivers the vaccine into the shallow layers of skin (intradermal).

DTP vaccine is administered to give protection against the bacterial diseases diphtheria (Corynebacterium diphtheriae) , tetanus (Clostridium tetani) and pertussis ( Bordetella pertussis). The vaccine consists of killed bacteria that is injected into the muscles of the forearm in children (intramuscular).
