Is monomeric on B cell surface

Is a potent complement activator

Crosses placenta

Is predominant antibody in secretion

Is predominant antibody in secondary immune response

Correct Answer: Is monomeric on B cell surface, Is a potent complement activator

Determine the correctness or otherwise of the following Assertion (A) and Reason (R).
Assertion: An antigen recognized by one immunoglobulin subtype is not recognized by any other subtype.
Reason: Immunoglobulin subtypes differ from each other both in the variable and in the constant regions.

Both (A) and (R) are true and (R) is the correct reason for (A)

Both (A) and (R) are true but (R) is not the correct reason for (A)

Both (A) and (R) are false

(A) is true but (R) is false
