B
It results in less antibody secretion.
C
It triggers fever.

Verified step by step guidance1
Understand the concept of a secondary humoral response: This is the immune system's response to a previously encountered antigen, where memory cells are already present.
Recall that memory cells are generated during the primary response and remain in the body to provide a faster and more efficient response upon re-exposure to the same antigen.
Recognize that a secondary humoral response is characterized by a rapid production of antibodies due to the presence of these memory cells.
Identify that the secondary response does not result in less memory-cell circulation or less antibody secretion; instead, it enhances these processes.
Conclude that the statement 'It occurs much more rapidly than a primary response' is characteristic of a secondary humoral response, as the immune system is already primed to respond quickly.
