I think the correct answer from the choices listed above is option B. If pink snapdragons of the F1 hybrids (RW) are crossed with red snapdragons of the parent plant (RR), the ratio of flowers produced in 40 offspring would be <span>20 pink flowers, 20 red flowers. This can be proved in by making a Punnett Square.</span>

The genotype of the F1 hybrid is RW.

The genotype of the parent plant is RR.

The percentage of offspring with particular genotype and phenotype can be determined using the   Punnett squares as shown in image.

The crossing between the F1 hybrid pink flower and parent red flower produces 50% of each red and pink type of flowers. Therefore, for 40 offspring, 50% each i.e. 20 red and 20 pink flowers will be produced.

Therefore, the correct answer is B.) 20 pink flowers, 20 red flowers.
