The correct answer is (b) False

To explain I would say: Primary immune response is the first immune response developed during the first encounter with the antigen. It is feeble but relatively longer. The secondary immune response is a quick heightened immune response against a subsequent encounter with the same antigen. It is due to the presence of memory cells against that antigen. Hence, the secondary response is more intense than the primary response.
