About what percentage of the geographical area of Bihar is covered by forest?

Correct answer: (b) 7%

Explanation

Only about 7–8% of Bihar's geographical area is under forest cover, far below India's average of about 21–22%. Bihar is a densely populated, largely farmed plain, and its forests are mainly in the Valmiki area of West Champaran, the Kaimur plateau and the hills of Munger, Jamui and Banka. Most of the old state's forests went to Jharkhand in 2000.
