The correct answer is: C. 98,000 sq. km.
Assam is a state in northeastern India. It is the largest state in the region by area, covering 78,438 sq. km. However, the area of Assam is often reported to be 98,000 sq. km. This is because the state’s boundaries have changed over time. In 1972, the Indian government created the new state of Meghalaya out of parts of Assam. This reduced Assam’s area by about 20,000 sq. km. However, the area of Assam is still often reported to be 98,000 sq. km., which is the area of the state before 1972.
The other options are incorrect. Option A is the area of the state of Nagaland, which is located to the north of Assam. Option B is the area of the state of Manipur, which is located to the east of Assam. Option D is not a valid option.
