Assertion (A) : The sun sets in Gujarat about two hours after Arunachal Pradesh.
Reason (R) : Arunachal Pradesh is on a higher latitude than Gujarat.

Select the correct option from the given alternatives.

  • A.Both (A) and (R) are true, and (R) explains (A)
  • B.Both (A) and (R) are true, but (R) does not explain (A)
  • C.(A) is true and (R) is false
  • D.(A) is false and (R) is true

Answer: B

The answer is both (A) and (R) are true, but (R) does not explain (A).

India spans about 30 degrees of longitude, from roughly 68 degrees E in Gujarat to 97 degrees E in Arunachal Pradesh. Since the earth turns 1 degree in 4 minutes, local time differs by about two hours, so the sun rises and sets in Arunachal about two hours before Gujarat (A is true).

Arunachal Pradesh does lie farther north (about 27 to 29 degrees N) than most of Gujarat (about 20 to 24 degrees N), so R is true too. But the time difference comes from the difference in longitude, not latitude, so R does not explain A.
