Correct answer: D
Concept
The Earth’s heat zones are broad latitudinal belts defined by the Tropics and the Polar Circles. Each Frigid Zone extends poleward from a Polar Circle: from 66½° N to the North Pole and from 66½° S to the South Pole.
Application
The northern polar-cap description covers 66½° N to 90° N, while the southern polar-cap description covers the Antarctic Circle at 66½° S to 90° S. Thus two listed descriptions belong to the Frigid Zones.
Contrast
The belt from 66½° N to the North Pole is the Northern Frigid Zone.
The belts from 23½° to 66½° in both hemispheres are the Temperate Zones.
The belt from the Antarctic Circle to the South Pole is the Southern Frigid Zone.
The statement ‘More than one of the above’ corresponds to the two polar-cap descriptions.
The statement ‘None of the above’ conflicts with the presence of both polar-cap descriptions.
Result
Both polar-cap descriptions fall under the Frigid Zone; therefore, ‘More than one of the above’ is the correct response.
