The correct answer is all round and yellow.

As you can see in the punnet square presented below, all of the offspring from the RRYY X rryy cross have the RrYy, heterozygote genotype.

Since R and Y are the dominant alleles, the heterozygotes express the same traits as the dominant parent, yellow and round seeds.
