Which of the following statements about time zones is true? A. Time zones are based on the days of the week. B. Time zones sometimes follow the borders of countries. C. Time zones’ boundaries are perfectly vertical lines (north to south). D. Time zones’ boundaries are perfectly horizontal lines (east to west). Please select the best answer from the choices provided

(B) Time zones sometimes follow the borders of countries

Explanation:

Let's prove why each other statement is false.

A: Time zones are based on hours and they are determined through lines of latitude (15 degrees longitude each). So this is false.

C: Time zones boundaries are not perfectly vertical, as all boundaries in the US alone are not vertical, they follow a jagged line. This is also false.

D: Time zones are based on lines of latitude, meaning they run North-South, so they cant run East-West. This is false.

This leaves B.
