Answer 1

Hint: 82°30' E is being considered as the Standard Meridian of India. This is because it is situated in the centre of all longitudes and latitudes in which India is located. This location lies almost in the centre of India.

Complete answer: The standard meridian of India is passing through the following 5 states:
Uttar Pradesh
Madhya Pradesh
Chattisgarh
Orissa
Andhra Pradesh

Additional Information: Some facts about Standard Meridian are as follows:
-The Standard Meridian of India is actually passing through Mirzapur in Uttar Pradesh. It is termed as the standard time for the whole country
-Standard time is meant for the synchronization of clocks within a certain geographical area towards a single standard time. It is always better, instead of using solar time or a locally chosen meridian.
-Such standard meridian is maintained in each and every country so that it is the central longitude of the whole country. It is the same time throughout the country

Thus, The correct option is D.

Note: The local time of the places are differing from one place to another. In India, we can find the difference of about 1 hour and 45 minutes in the local times of places in Gujarat with places in Dibrugarh of Assam. Thus, it is necessary to adopt the local time of some central meridian of a country as the standard time for the country. The local time at this meridian is termed as the standard time for the whole country.
