A) BRCA1; most common
B) Ras; most common
C) BRCA1; least common
D) Ras; least common
E) BRCA2; most common
Oncogene
An abnormally functioning gene implicated in causing cancer. Compare with proto-oncogene and tumor suppressor gene.
Cell Signaling
Mechanisms of communication between cells. Cells signal one another with secreted signaling molecules, or a signaling molecule on one cell combines with a receptor on another cell. See signal transduction.

Final Answer :
B
Explanation :
The Ras oncogene is one of the most common oncogenes involved in human cancer. It plays a crucial role in cell signaling pathways that control cell growth and differentiation, and mutations in Ras genes can lead to uncontrolled cell proliferation, a hallmark of cancer.
