(C) The genotype of the heterozygous parent is $Rr$.When this plant is selfed $(Rr \times Rr)$,the resulting progeny genotypes are $RR, Rr, Rr, rr$.The phenotypic ratio is $3$ round : $1$ wrinkled.The parental phenotype is 'round' (since the parent is heterozygous for round seeds).Out of the total $1600$ seeds,the number of round-seeded plants is $\frac{3}{4} \times 1600 = 1200$.Therefore,$1200$ seedlings will exhibit the parental phenotype.
