contains fertile farmland and produces 85% of the carpet sold in the US.

A.
Ridge and Valley
B.
Coastal Plain
C.
Blue Ridge
D.
Appalachian Plateau

B. Coastal Plain

The correct answer is B. Coastal Plain.

To determine the correct answer, we need to look for information about a region that contains fertile farmland and is a major producer of carpets sold in the US.

First, let's examine option A: Ridge and Valley. The Ridge and Valley region is known for its mountains and valleys, but there is no specific mention of fertile farmland or carpet production in this region.

Moving on to option B: Coastal Plain. The Coastal Plain region stretches along the Atlantic coast and is characterized by flat, fertile land. It is possible that this region could contain fertile farmland, but we still need to determine if it is a major producer of carpets in the US.

Next, let's consider option C: Blue Ridge. The Blue Ridge region is known for its scenic mountain range, but again, there is no specific mention of fertile farmland or carpet production in this region.

Finally, we have option D: Appalachian Plateau. The Appalachian Plateau is a region located in the central eastern part of the United States. While it may not be typically associated with fertile farmland, it is noteworthy that the option mentions it produces 85% of the carpet sold in the US. This suggests that the Appalachian Plateau is a major carpet producer, even though it may not have fertile farmland.

Based on the information provided, it seems that the correct answer is D: Appalachian Plateau.
