The Benthic zone would most likely be the part of a like wherein it is mostly aphotic in nature. In addition, the benthic zone is usually located at the bottommost layer of the lake wherein it is usually characterised by having sediments that support huge amounts of vegetation on the layer.
The aphotic zone is the part of the lake or ocean which receives very little or no sunlight. It is usually found in the regions of oceanic depths where only 1% of the sunlight penetrates. Due to lack of proper sunlight no photosynthesis occur in this region.
The benthic zone is the lowest level of the oceanic or lake water body, it receives very little or no sunlight. The zone remains dark without light. The animals exhibit special adaptation called as bio luminescence for producing their own light to search food and mates.
On the basis of the above explanation, Benthic zone is the most likely to be aphotic.
