Answer:
c. "short, long"
Explanation:
The question being described involves two different genes; one coding for beans length and the other for pod length. According to the question, beans may be tall (T) or short (t) while they can also have have long (L) or stubby pods (l).
From the phenotypic ratio result of the F1 generation, which were all tall and stubby, it is clear that tall bean (T) and stubby pods (d) are highest balloon. According to Gregor Mendel's ratio of dihybrid cross; 9.3.3:1, the least occuring phenotype, which is 1 of 16, can be "short, long".

Polyploidy (more than two complete sets of chromosomes) is not rare among plants. For example, pollen grains may reach female flowers via animals or wind. In some cases, pollen grains from species with 4 complete sets of chromosomes will have 2 sets of chromosomes. Pollen grains may fuse with a female reproductive organ with 1 set of chromosome (so, female plant must have 2 sets of chromosomes). The resulting zygote will have 2 + 1 sets of chromosomes, so the plant will have 3 complete sets of chromosomes.
