India's north-south extent is greater than east-west extent, yet why is time difference mainly linked with the east-west direction?

Answer and explanation

Correct answer: Time changes with longitudes, not latitudes

Local time is governed by longitude because Earth rotates from west to east and different meridians face the Sun at different moments. Earth turns through 360 degrees in about 24 hours, so 15 degrees of longitude represents roughly one hour of time difference. A north-south change mainly changes latitude, which affects the angle of solar rays and climate, but it does not normally create a direct local-time difference. Therefore, option A is correct: India's east-west span crosses different longitudes, whereas its north-south span mainly crosses latitudes. The other options confuse time with coastline, deny the presence of latitudes, or wrongly define extent as area.
