a
b
c
d

Explanation:

Cancers are mainly classified based on the type of tissue they originate from. For example, carcinomas (from epithelial tissue), sarcomas (from connective tissue), etc. Growth rate (B) is more related to tumor grade/stage in some contexts but not the primary classification basis. The number of organs affected (C) is about metastasis/spread, not classification. Cell size (D) is not the key factor for cancer classification.

Answer:

A. Cancers are classified according to the type of tissue they affect.
