Advika took a Croton plant with shaded leaves and set up an experiment as shown here. She kept the plant first in darkness for a few hours and then placed it in sunlight. After 6 hours, she performed iodine test on plucked leaves P, Q and R. Which of the following is the possible outcome? (Note : Shaded portion in the question figure indicates green colour and in the options, it indicates blue-black colour.)


A - Leaf Q
B - Leaf Q
C - Leaf R
D - Leaf P


Correct answer is D since the CO2 obsorbent is present in Leaf P.When the outer circle is not present,it does not mean the leaf cannot prepare starch.The picture depiction is confusing.
