Answer
A type of white blood cell
Explanation
## Step 1: Understanding the context.Lymphocytes are specialized cells involved in immune defense. They are principal actors of specific defence (adaptive immune response) and constitute approximately 20-45% of total circulating white blood cells in blood.## Step 2: Classifying from the options. Let's go over each of these options:1. A type of bacteria - Lymphocytes are immune cells in the body, not a type of bacteria.2. A type of antibody - Antibodies are proteins produced by one type of lymphocyte (B cell), they are not lymphocytes themselves.3. A type of white blood cell - This seems plausible because lymphocytes represent a category of white blood cells.4. A type of virus - Viruses are pathogens, they infect entities like lymphocytes, but are not themselves lymphocytes.5. An antigen - Antigens are foreign substances provoking immune response, and lymphocytes get activated by antigens, but are not antigens themselves.
