i think A

blues · Answer

First of all, it tells you that the parent plants are both heterozygous. So what are their genotypes?

blues · Answer

Both parents are Ss. Heterozygous means one big S and one small s.

Only one of your four options has both parents S/s and S/s.

blues · Answer

And it isn't A.

anonymous · Answer

B

blues · Answer

It isn't B either. B has one parent SS and the other Ss.

You're looking for the option where BOTH parents are Ss and Ss...
