A.
2 RR: 1 Rr: 1 rr would be the genotype ratio. 2 red: 1 pink: 1 white would be the phenotype ratio.
B.
1 RR: 1 Rr: 2 rr would be the genotype ratio. 1 red: 1 pink: 2 white would be the phenotype ratio.
C.
2 RR: 2 Rr: 0 rr would be the genotype ratio. 2 red: 2 pink: 0 white would be the phenotype ratio.
D.
1 RR: 2 Rr: 1 rr would be the genotype ratio. 1 red: 2 pink: 1 white would be the phenotype ratio.

Cross Rr × Rr gives genotypes 1 RR : 2 Rr : 1 rr (Punnett square). With incomplete dominance (R = red, r = white, Rr = pink) the phenotypes are 1 red : 2 pink : 1 white.
