Answer:

C

Step-by-step explanation:

The correct answer would be a genotype that was different from that of both parents.

Let us assume that the allele for height is A (for tall) and a (for short). Homzygous tall plant would have the genotype AA while homzygous short plant would have the genotype aa. Crossing both genotypes:

AA x aa

Aa Aa Aa Aa

All of the offspring, even though have the same phenotype as one of the parents, have unique genotype from either of the parents. While the parents are AA/aa, the offspring are Aa.

The correct option is, therefore, C.
