Solution

The correct option is A
Memory B cell and Plasma Cells

There are millions of B cells that are present in the lymph nodes that have never encountered an antigen before. These B cells are called naive B cells. On encounter with the antigen, the naive B cell divides rapidly to form Plasma B cells and Memory B cells. The Plasma B cells produce million of antibodies to fight the infection. Memory B cells on the other hand remember the antigen and help in providing a heightened immune response on encountering the antigen again.
