Assertion : Subsequent encounter with the same pathogen elicits a highly intensified anamnestic response.
Reason : This is based on the fact that our body appears to have memory of the first encounter.

Consider the following four statements (a-d) and select the option which includes all the correct ones only: a) B-lymphocytes forms cellular barrier of innate immunity. b) HLA antigens are called as transplantation antigens c) Subsequent encounter with the same pathogen elicits a highly intensified anamnestic response. d) Interferons protect non-infected cells from further viral infection.
