B. Granulocytes and agranulocytesExplanation
Granulocytes and agranulocytes are the two main categories of leukocytes. Granulocytes are characterized by the presence of granules in their cytoplasm, which can be stained and observed under a microscope. They include neutrophils, eosinophils, and basophils. Agranulocytes, on the other hand, do not have visible granules in their cytoplasm. They include monocytes and lymphocytes. This categorization is based on the presence or absence of granules and helps in identifying and classifying different types of white blood cells.Rate this question:

Correct Answer
C. YearsExplanation
Lymphocytes are a type of white blood cells that play a crucial role in the immune system. They are responsible for recognizing and destroying pathogens and infected cells. The life span of lymphocytes varies depending on the type. While some lymphocytes, such as natural killer cells, have a short life span of only a few days, others, such as memory B and T cells, can live for years. These long-lived lymphocytes help provide long-term immunity against previously encountered pathogens. Therefore, the correct answer is "Years."Rate this question:
