Solution

The correct option is C Starch synthesis in pea : Multiple alleles
Starch synthesis in pea plants is controlled by a single gene that has two alleles - B and b. The BB homozygotes can produce starch more effectively and thus large starch grains are produced.The bb homozygotes can produce starch less effectively and thus small sized starch grains are produced.
