The answer to this question is Paradoxical sleep.
Paradoxical sleep is the stage of sleep where in the person’s muscles are
relaxed and this is the stage that is called a dreaming sleep. In this stage of
sleep the person is in deep sleep state.
The correct answer is option C, that is, it prevents the formation of ATP and NADPH, which are needed by the light-independent reactions to make sugars.
The herbicide atrazine combines with the D1 protein and inhibits the binding of plastoquinone. By obstructing the binding of plastoquinone, the procedure of photosynthetic transfer of electron is disturbed, and thus, the production of ATP and NADPH in the chloroplast gets compromised.
This leads to an incapacity to fix carbon dioxide and generate the nutrients required for the plant to live. The block in the transfer of electrons also results in an oxidative stress and the production of radicals that lead to brisk cellular destruction.
A Eukaryote has a nucleus.
