Assertion (A): Overexpression of Bcl-2 can contribute to cancer.
Reason (R): Cells that should have been eliminated by apoptosis survive instead.

  • A.A is true but R is false
  • B.A is false but R is true
  • C.Both A and R are true, and R is the correct explanation of A
  • D.Both A and R are true, but R is not the correct explanation of A

Answer: C

Both are true and the reason gives the route: a cell carrying damage would normally be removed, and blocking that removal lets damaged cells accumulate and acquire further mutations. Evading apoptosis is counted among the hallmarks of cancer.
