Is There Photosynthetic Activity in the Benthic Zone of the Ocean

Is there photosynthetic activity in the benthic zone of the ocean?

A) No, because nutrient availability is too low.
B) No, because this is below the photic zone.
C) Yes, because this is the zone of high light penetration and photosynthetic activity.
D) Yes, because this is the richest zone for nutrient turnover due to microbial activity.
E) Yes, because high light and high nutrient conditions are optimal for phytoplankton production.
