Detailed explanation-1: -T-lymphocytes are involved in providing cell-mediated immunity not B-lymphocytes Hence, the statement is False.
Detailed explanation-2: -The B Cells have the ability to transform into plasmocytes and are responsible for producing antibodies (Abs). Thus, humoral immunity depends on the B Cells while cell immunity depends on the T Cells.
Detailed explanation-3: -B lymphocytes, also called B cells, create a type of protein called an antibody. These antibodies bind to pathogens or to foreign substances, such as toxins, to neutralize them. For example, an antibody can bind to a virus, which prevents it from entering a normal cell and causing infection.
Detailed explanation-4: -The correct answer is option 4. B cells and T cells are the main types of lymphocytes. B cells work chiefly by secreting substances called antibodies into the body’s fluids. Antibodies ambush antigens circulating the bloodstream.
