A geneticist made a cross between plants with smooth seeds, each with a gene that consisted of the alleles SS, and plants with wrinkled seeds, each with a gene that consisted of the alleles ss.

What will be the phenotype of the resulting F1 plants? The allele S is dominant to the allele s.

A.

All smooth seeds.

B.

All wrinkled seeds.

C.

One half smooth and one half wrinkled seeds.

D.

3/4 will have smooth seeds, 1/4 will have wrinkled seeds.

Yes you are correct because

and since anytime you have a big S (Smooth) then it overrides anything else, and you don't have to look at the second allele, however the only way you can get wrinkled seeds is if you have two small "ss", which is not possible in this question, because you will get a big "S" in every square.
