Specific Immune Response Question

VCAA 2007 MC 18

A specific immune response involves:
A. Helpter T lymphocytes releasing cytotoxins.
B. T lymphocytes recognising antigens presented by macrophages.
C. Suppression of the response by memory B cells after the infection.
D. B lymphocytes, each with a number of different surface antibodies.

The answer is B, but why isn't D a part of the specific immune response?

Because it isn't a response, more just a description. Whereas B is a response from the T cells :)

It's because D is wrong and B cells don't have "a number" of different surface antibodies, they have a single surface antibody specificity that's present in large numbers.

This is the real reason. Take note.

Often questions like this will make specific things look non-specific and vice versa. Just get comfortable with what is specific and what is non-specific.

A - wrong because T-cells don't release cytotoxins, they just make T - cells clone and expand into them + memories ?
B -

C  - what does this even mean ;D
D - Only 1 antibody per B cell?

Just making sure I am on the same track as you guys!

A - helper t cells don't do anything related to 'destroying infections' more so setting up the response
B - correct answer, t helper cells recognize the antigens on the APC (macrophage in this instances)
C - suppression is done my T regulator cells, not memory cells
D - B cells have a specific antibody not multiples of different antibody's

just as a guide for someone who still isn't sure
