The latitudinal extent of Bihar is approximately:

24°N to 27°N
20°N to 24°N
27°N to 30°N
19°N to 23°N

The correct answer is: a) 24°N to 27°N.

Bihar is a state in eastern India. It is bordered by Nepal to the north, Uttar Pradesh to the west, Jharkhand to the south, and West Bengal to the east. The state has a total area of 94,163 square kilometers (36,357 sq mi).

The latitudinal extent of Bihar is approximately 24°N to 27°N. The state’s capital and largest city is Patna.

Option b) 20°N to 24°N is incorrect because it does not include the northernmost point of Bihar, which is located at 24°N.

Option c) 27°N to 30°N is incorrect because it does not include the southernmost point of Bihar, which is located at 23°N.

Option d) 19°N to 23°N is incorrect because it does not include the westernmost point of Bihar, which is located at 24°N.
