Answer:
A compound formed in solution from the negative ion of an acid and the positive ion of a base is a salt. Hence the answer is option A
Explanation:
Salt is a product which is formed when a base is reacted with an acid. This reaction is also known as neutralization reaction because the base neutralizes the acid and the acid neutralizer base. By the course of action of these two salt is formed which is sour in taste.
This salt gets deposited in the base of the container as a form of precipitation. The salt can be of different color depending upon the color of base and acid which was used during the chemical reaction.

Viral antigens like EBV are usually recognized by T cells involving an antigen fragment present within class I MHC to the T cell receptor.
Ebstein Barr Virus
The Epstein-Barr virus is a human herpes virus with unusual biological characteristics.
- It lives in practically every human person in a dormant condition in resting memory B lymphocytes
- It is also a strong transforming virus in vitro for B cells and is linked to numerous significant lymphomas, including Burkitt's, Hodgkin's disease, and immunoblastic lymphoma.
With the exception of the memory compartment, each stage of the cycle has been shown to be possibly controlled by the immune response.
Epstein-Barr virus (EBV), commonly known as human herpes virus 4, is a double-stranded DNA herpes virus that is extensively spread. It is the cause of infectious mononucleosis.
- EBV is most usually transmitted by body fluids, particularly saliva. EBV, on the other hand, can transmit by blood and sperm during sexual intercourse, blood transfusions, and organ transplants.
EBV can be transferred by utilizing materials that have recently been used by an infected individual, such as a toothbrush or a drinking glass.
- The virus is likely to survive on an object for at least as long as it is wet.
- When you initially get infected with EBV (primary EBV infection), you might spread the virus for weeks or even months before you notice any symptoms.
- Once the virus has entered your body, it remains dormant.
Hence, the correct answer is option A
