Leukemia is a type of cancer that affects:

  1. Skin cells

  2. Bone marrow

  3. Leukocytes

  4. Lymphatic system

The correct answer is: Leukocytes

Leukemia is a type of cancer that affects the blood and bone marrow. Specifically, it originates in the tissues responsible for the production of blood cells, such as leukocytes (white blood cells). Leukocytes are a crucial part of the immune system, and when leukemia affects them, it disrupts the normal functioning of the immune system and blood production. Therefore, the correct answer is C - Leukocytes. Option A (Skin cells), Option B (Bone marrow), and Option D (Lymphatic system) are incorrect because leukemia primarily affects the white blood cells (leukocytes) and not the skin cells, bone marrow, or the lymphatic system directly.
