What is the most common site of metastasis for a conjunctival melanoma?

Explanation:
The key idea here is how conjunctival melanoma tends to spread when it becomes systemic. When distant metastasis occurs, the liver is the most frequently involved organ. Melanoma cells can reach the liver through the bloodstream, and the liver’s rich blood supply makes it a common “landing spot” for circulating tumor cells. So, among distant sites, the liver stands out as the most common metastasis site. Lungs, brain, and bone can also be affected by metastases from conjunctival melanoma, but they are less common as first distant sites compared with the liver. This pattern helps explain why the liver is the best answer.
