What do B Cells do when they encounter an antigen?
A
Produce antibodies
B
Die
C
Split
D
Produce antigens
Explanation: 

Detailed explanation-1: -B cells have B cell receptors (BCRs) on their surface, which they use to bind to a specific protein. Once the B cells bind to this protein, called an antigen, they release antibodies that stick to the antigen and prevent it from harming the body.

Detailed explanation-2: -When a B cell encounters an antigen, it is stimulated to mature into a plasma cell or a memory B cell. Plasma cells then release antibodies (also called immunoglobulins, or Ig). There are 5 classes of antibodies-IgM, IgG, IgA, IgE, and IgD.

Detailed explanation-3: -Typically, the events of B-cell activation in vivo take place in specialized secondary lymphoid tissues such as the lymph nodes to increase the likelihood of a B cell ‘finding’ its cognate antigen [5]. Lymph nodes are supplied with lymphatic fluid through the afferent vessel.
