- A. Liver
- B. Reproductive tract
- C. Colon
- D. White blood cells (WBCs)
Correct Answer: A
Rationale: The liver is one of the most common sites for metastasis of cancer cells. This is because the liver receives a high volume of blood flow, making it a common site for cancer cells to spread through the bloodstream. Additionally, the liver's function in filtering toxins and foreign substances from the blood makes it a favorable environment for cancer cells to establish secondary tumors. Monitoring the liver for metastasis is crucial in cancer diagnosis and management.
