A
ability to enter the thyroid
B
degree of aggregation
C
dose
D
size
Explanation: 

Detailed explanation-1: -These antigens stimulate a number of cells in the immune system, including macrophages, T cells, and B cells. An immune response begins when macrophages ingest antigens such as proteins entering the body and digest them into antigen fragments.

Detailed explanation-2: -To be able to destroy invaders, the immune system must first recognize them. That is, the immune system must be able to distinguish what is nonself (foreign) from what is self. The immune system can make this distinction because all cells have identification molecules (antigens) on their surface.
