Well I think it's gonna be C - 90° N and 90 ° S - because those latitudes are located exactly on both north and south poles and there's nothing more likely to see glaciers than the poles themselves.
The latitudes most likely to see glaciers are 90° N and 90° S, which correspond to the North and South Poles. These areas maintain extremely cold temperatures, allowing for the formation and persistence of glaciers. Therefore, the correct answer to the question is C.
