Answer:
Answer : Scientific theories are rigorously supported by numerous studies, and are hypotheses that, even up till date, have never been disproved.

Evolution can be described as changes that occur in the heritable characters over a period of time. This usually occurs through natural selection.

C. tumor suppressor
Explanation:
Tumor suppressor genes encode for proteins which inhibit cell proliferation in some way. One copy of this gene is sufficient to control cell proliferation so both the alleles must be mutated to promote tumor development. Mutation may be a deletion or point mutation.
Tumor suppressor genes are known to code for five classes of proteins:
- Intracellular proteins which inhibit cell proliferation through specific stage of cell cycle
- Receptors for hormones that inhibit cell proliferation
- Apoptosis promoting proteins
- Enzymes involved in DNA repair
- Check point control proteins that arrest cell cycle on detecting any abnormality
