Final answer:
Chemotherapy drugs, including plant-derived alkaloids, may cause damage to bone marrow and the digestive system due to their impact on rapidly dividing cells.
Step-by-step explanation:
Plant-derived alkaloids used in chemotherapy carry a risk of damage to various tissues due to their non-specific nature. The most affected tissues are those with rapidly dividing cells. These include the skin, hair, gastrointestinal tract, and bone marrow because chemotherapy drugs generally target and interfere with cell division, impacting both cancerous and healthy cells. As a result, patients may experience side effects like damage to the digestive system.
Therefore, the correct answer to the student's question is c) Bone marrow and digestive system.
