Step-by-step explanation:

Correct answer would be B.

When it comes to terms and understanding them better:

T marks tumor, N marks node and M marks metastasis. 0 signifies that there is no presence of mentioned terms. Tis means carcinoma in situ.

This means, there are no abnormal lymph nodes, it means there is no metastasis, no carcinoma.

Also, there are no traces of tumor. if there is tumor and lymph nodes, and if there is no evidence, the terms are: tx, nx, m0.
