Answer:
The correct option is A) swamp sediments
Explanation:
A swamp can be described as an area which is present near a river or a stream. When the rivers pr the stream floods, these areas get enormous nutrients and chemicals from the water. As a result, these areas are much richer in chemical compounds as compared to the other land areas. Hence, these areas will be most suitable for the growth of autotrophs which need chemical compounds as a source of energy. Hence, option A is correct.
