How does the diversity of life in the sublittoral zone compare to that of the upper intertidal zone?

The correct option is this: THERE IS MORE BIODIVERSITY IN THE SUBLITTORIAL ZONE COMPARE TO THE UPPER INTERTIDAL ZONE BECAUSE THERE IS LESS TEMPERATURE VARIATION IN THIS REGION.
The sublittorial zone refers to the part of the ocean that is about 200 meters away from the surface. The zone is characterized by constant temperature as a result of the constant sunlight that reaches the depth; this leads to more biodiversity in this zone.

The upper intertidal zone is the part of the shore that is covered by water only at high tide. The sublittoral zone is the shallow part of the ocean extending out to the edge of the continental shelf, that is, the part where sunlight penetrates all the way to the sea floor. Of the two, the upper intertidal zone features a greater diversity of species, perhaps because its sometimes harsh and changeable environment presents a greater variety of niches and requires a greater variety of adaptation in order to ensure survival.

Is their a picture that goes along with it? ?
