Which part of the seafloor contains the thickest sediment layer?

The seafloor exhibit thickest sediment layer near the continents.

Explanation:

In the seafloor the sediments are laid down in the form of strata or layer, in the body of water. Sediments are found to be thinnest near the spreading centers and found thicker away from the ridge.

At the ridge the seafloor accumulates more sand, organic sediments from aquatic plants and animals as the time passes. But the sediments are the thickest near the continents.
