Detailed Solution

Due to India's length, there is a two-hour time difference between Gujarat and Arunachal Pradesh. Gujarat is located in India's far western region. The state of Arunachal Pradesh is located in India's far east. Instead of using solar time or a locally selected meridian to generate a local mean time standard, we use standard meridian, which refers to harmonising clocks within a certain geographic region to a single standard time. Option (a) is the appropriate response since both the stated claim and the justification are true, and the justification is the proper justification for the assertion. With a longitude of 82°30'E, the standard meridian of India runs through Mirzapur in Uttar Pradesh, not Banaras, but rather close to Allahabad. Therefore, both assertion and reason are true and but the reason is not the correct explanation of assertion.
