• C. metastasis
• D. differentiation

Answer: (C)

Verified step by step guidance

1. Step 1: Begin by understanding the key terms provided in the problem. Angiogenesis refers to the formation of new blood vessels, apoptosis is programmed cell death, differentiation is the process by which cells become specialized, and metastasis is the spread of cancer cells to other parts of the body.
2. Step 2: Focus on the definition of metastasis. Metastasis occurs when cancer cells break away from the original tumor, travel through the bloodstream or lymphatic system, and establish new tumors in other parts of the body.
3. Step 3: Compare the definitions of the other terms to ensure they do not match the description of cancer cells spreading to other locations. For example, angiogenesis is related to blood vessel formation, not cell spreading.
4. Step 4: Eliminate the incorrect options (angiogenesis, apoptosis, differentiation) based on their definitions and relevance to the problem.
5. Step 5: Conclude that the correct term describing the spread of cancer cells to other locations in the body is metastasis.
