Explanation:

Identify the features of the margin

The diagram shows a passive continental margin with three distinct zones.
We first identify the shallow, gently sloping region near the shore.
This flat, shallow region represents the Continental Shelf.

Locate the steep descent

Next, we observe where the gradient increases sharply.
This steep drop-off represents the Continental Slope.

Locate the continental rise

Finally, we identify the transition zone at the base.
The Continental Rise is the gently sloping region of sediment accumulation.
It lies at the base of the Continental Slope before reaching the abyssal plain.
This is located at the bottom-right curve of the gray profile.

Answer:

The continental rise is located at the base of the steep continental slope, where the steep incline flattens out into a gentle curve at the bottom-right of the gray seafloor profile (just before it reaches the deep ocean floor).
