Answer:

B. First 200 feet

Explanation:

The first 200 feet deep zone of the ocean is termed as Photic Zone of the ocean because this zone receives sufficient quantities of light so that the phytoplanktons that are found in this are become enable for Photosynthesis. This zone is critically important because we know that phytoplanktons are the primary producers in oceans and the food web of the ocean starts with these phytoplanktons. This zone is considered to be the area of highest net primary productivity.
