which is one quality of the entire open - ocean zone?\no few nutrients\no low pressure\no ample sunlight\no…

Brief Explanations:

The open - ocean zone is vast and has limited nutrients as most nutrients sink to the ocean floor or are concentrated near the shore. Pressure increases with depth in the ocean, so low pressure is incorrect. Only the upper layers of the open - ocean receive ample sunlight, not the entire zone. Salinity is relatively stable in the open - ocean compared to some coastal areas.

Answer:

A. few nutrients
