Flower color in four o clock plant is an example of incomplete dominance wherein homozygous dominant (RR) gives "red" phenotype, heterozygous dominant (Rr) gives pink and homozygous recessive (rr) gives white phenotype. The genotype of parents is Rr (pink) and rr (white). The phonotypic ratio of progeny will be 1 pink: 1 white. Thus, the correct answer is option C.

gametes rr

Rr r

R Rr (pink)

r rr (white)

The Four O'Clock plant is the case of incomplete dominance.

The homozygous individuals have the following colors:

RR: The flower is Red.

WW: The flower is White.

The red color is incompletely dominant over the white color.

Hence, the progenies in the F1 generation, between the cross of homozygous red and white flower is pink.

The genotype of the pink color flower is RW.

The possible outcome of the cross between two pink four o'clock flower plants is shown as follows:
