B cells start to proliferate in response to an invasion by antigens. They produce a generation of plasma cells which actively secrete antibodies in body fluid.
Explanation:
Antibodies are globulin type proteins. Each B cell can generate only a single type of antibody against a particular foreign antigen, to which it was first exposed.

Answer:

GACCTG (the fourth option)

Explanation:

To find the correct complementary strand, we need to know this simple rule:

T always pairs with A and C always pairs with G.

So whatever letter you have in the DNA strand, the complementary strand will have the complement to it. In this case, we have CTGGAC. The complement of C is G, for T it is A, and so on. Therefore, the correct complementary strand is GACCTG (the fourth option).
