A Member of Your Research Group Isolates a Mutant Plant

A member of your research group isolates a mutant plant from a species with perfect flowers, but this plant does not produce sporopollenin.He would like to further characterize this mutant by studying its offspring.What do you tell him?

A) It will be impossible to study the offspring of this mutant, because it will not be able to develop seed coats to protect its seeds.
B) It will be impossible to study the offspring of this mutant, because the pollen will not be protected from desiccation and will not be viable.
C) This mutant will only produce offspring if it is pollinated it with pollen from a nonmutant plant of the same species.
D) This mutant will only produce offspring if you use its pollen to fertilize a plant with a functional sporopollenin gene.
E) This mutant should be able to produce viable offspring if the flowers are self-pollinated.
