Final answer:
The correct mini-concept map with proper linkage in describing cancer genesis is option c.
Step-by-step explanation:
The mini-concept map that has correct linkage in describing cancer genesis is option c. It includes the following linkages: oncogene - clonal proliferation - increased cellular differentiation - cancer.
These linkages represent the multi-step process of carcinogenesis, where normal cells are transformed into cancer cells. The oncogene promotes clonal proliferation, leading to increased cellular differentiation, which eventually results in cancer.
