Answer: The correct answer is: sunlight does not reach the bottom.

Explanation:

Plants are unable to grow at the bottom of lakes due to the inability of sunlight to reach the great depth (bottom) of most lakes.

Also sunlight necessary for food production can ONLY be trapped by the green coloured pigment, chlorophyll found in plants, and an inability of sunlight to reach the bottom would mean lack of food nutrients for plants at the bottom of lakes - thus, leading to no growth of plants at the bottom of lakes
