Answer:
(C). it occurs in somatic cells and thus are not usually transmitted to descendants
Step-by-step explanation:
Mutations are permanent changes in the genetic material due to alterations in the sequences of DNA molecules. Mutations may be classified as somatic or inherited (or germline).
Somatic mutations are those mutations that develop in somatic cells and cannot inherit from parents to their offspring.
Inherited mutations are those mutations that arise in sex cells or gamete-forming cells and transfer from parents to their offspring as these cells form mutated gametes.
A carcinogenic (cancer-causing) mutation is non-inheritable, if it occurs in normal body cells or somatic cells.
Thus, the correct answer is option (C).
