Mutations in dna found in which cells are most likely to have significant evolutionary consequences?

Mutations in gamete cells.

Explanation:

Mutations in gamete cells, called germinal mutations, occurs in reproductive cells that fully develops to ovum and sperm. When a mutated sperm or egg cell (genetically altered) come together to form a zygote during fertilization, they pass down that mutation to their offspring and it stands a chance of being inherited by future generations. It is through random germinal mutations that evolution occurs.

i think that c)gold was found there

but i am not sure

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
