- APleiotropic mutation
- BMultiple mutation

- DMonogenic mutation
Explanation:
A mutation that affect more than one characters simultaneously is known as pleiotropic mutation.
When mutation in single gene alter the trait, it is called monogenic mutation and the related disorder is monogenic disorder.
Polygenic mutation includes mutation in alleles of different genes that govern a common character.
