Answer:

20 large size leaves plants

40 medium sized leaves plants

20 small sized leaves.

Explanation:

PP = large leaves

P'P' = small leaves

PP' = medium leaves

PP' was crossed with another PP' plant:

PP' x PP'

progeny = PP, 2PP', and P'P'

PP = 1/4 x 80 = 20 large size leaves plants

PP' = 1/2 x 80 = 40 medium sized leaves plants

P'P' = 1/4 x 80 = 20 small sized leaves.

Hence the phenotypes would be:

20 large size leaves plants

40 medium sized leaves plants

20 small sized leaves.

(If it’s not be then is 100% C but B makes more sense)

Hope this helps
