Solution

The correct option is B IgA
Immunoglobulin A is an antibody that plays a crucial role in the immune function of mucous membranes. The amount of IgA produced in association with mucosal membranes is greater than all other types of antibody combined. It is the main immunoglobulin found in mucous secretions, including tears, saliva, sweat, colostrum and secretions from the genitourinary tract, gastrointestinal tract, prostate and respiratory epithelium. It is also found in small amounts in the blood. Hence it provides immunity to the digestive tract as it is made up of a mucous membrane.
So, the correct answer is 'IgA'.
