What is the most important geographical effect of India's longitudinal extent from 68°7'E to 97°25'E?

Answer and explanation

Correct answer: Difference in local time between east and west

The governing concept is that Earth rotates 360° in about 24 hours, so every 15° of longitude represents roughly one hour of time. India extends across about 29°18′ of longitude, which produces nearly two hours of difference in local solar time between its eastern and western extremes. Sunrise therefore occurs earlier in the east than in the west. India uses a single Standard Meridian, 82°30′E, to maintain one official time throughout the country. Option A is correct because it directly describes this effect. The other options confuse longitude with seasons, coastline, or area and have no logical connection with east-west extent.
