Option b is the correct answer.
Memory cells are the cell types that are produced during primary response to a virus and provide a swift response to the same virus.
When a virus a attacks a cell memory cells are produced and these in turn produce antibodies to the attacked virus. These memory cells remember or in a way gain some immunity to the virus attacked and when the same virus attacks the body for the second time these cells are produced during primary response to the virus and destroy it.
