Solution

The correct option is A $Y Y R r$
The dihybrid cross is a cross between two different lines/genes that differ in two observed traits. In the Mendelian sense, between the alleles of both these loci, there is a relationship of complete dominance - recessive. The cross produced variants which can be only possible if the parent was of YYRr nature.
So the correct option is 'YYRr'.
