Solution
The correct option is A 15°
The earth covers an angle of 360° with every rotation within the span of 24 hours. This indicates that it rotates by 15° every hour. Thus, for the purpose of convenience, time zones have been split into 24 equally-spaced time zones although there exist exceptions that consider political boundaries.
