Answer:
The physical feature circled 1 is the southern alps (B)
Explanation:
The question is incomplete without the image of satellite map of New Zealand.
Let's consider the description of each New Zealand physical features in the options:
The Northern Peninsula:
A peninsular is a piece of land that has its border mostly surrounded by water. The northern peninsular in New Zealand is located in the far north of the northern North Island.
This goes in line with option 2 (is a peninsula along the northern section of the island)
The Southern Alps:
It is a mountain range that extends along most of the length of New Zealand's South Island. It reaches its greatest elevations near the range's western side.
This goes in line with option 1 (is a mountain area along the western coast). Since this is the description of option 1, the physical feature is the southern alps
The Canterbury Plains:
It is a lowland area of east-central South Island in New Zealand.
This goes along option 4 (is a flat area along the southeast coast)
The Eastern Hills:
This is ruled out as the name implies a hill. A hill is an area of land that extends above surrounding land.
The Eastern Hills tracks extends from the Bus Barn in Eastbourne to Upper Hutt.
