See the following experiment and observe the result

Now identify plant (P-I,and II III)

Options

A. P - I = Long day plant, P - II = Long day plant, P - III Day neutral plant
B. P - I = Short day plant, P – II = Short day plant, P - III = Day neutral plant
C. P - I = Short day plant, P - II = Long day plant, P - III Day neutral plant
D. P - I = Long day plant, P - II = Short day plant, P - III = Day neutral plant

Answer

D

Explanation

Long day plants: These plants flower when they receive long photoperiods or light hours which are above than a critical period.
Short day plants: These plants flower when they are exposed to a photoperiod shorter than a critical period.
Day-neutral: These plants do not show any correlation between exposure to light duration and induction of flowering response.
