Detailed Solution

Gujarat is situated in the extreme west, and Arunachal Pradesh in the extreme east have a time lag of 2 hours. It means the sun rises 2 hours earlier in Arunachal Pradesh than in Gujarat. So, the Assertion (A) is correct.
India follows the same standard time for the whole country. The time along the Standard Meridian of India (82°30'E) passing through Mirzapur (in Uttar Pradesh) is the national standard time. The local time varies from one place to the next. To follow uniform time across the country, a standard meridian is established. It is known as Indian Standard Time. So, Reason ( R) is also correct but is not the correct explanation of (A).
