The correct answer is: B. 7,248 sq km
As per India State of Forest Report, 2017, the total recorded forest area of Bihar is 7,248 sq km. This is equivalent to 7.24% of the total geographical area of the state. The forest cover in Bihar has been increasing steadily over the years, from 6,877 sq km in 2015 to 7,248 sq km in 2017. This increase is due to a number of factors, including afforestation, natural regeneration, and the conversion of non-forest land to forest land.
The increase in forest cover in Bihar has a number of benefits. It helps to improve the environment by reducing air pollution, providing habitat for wildlife, and conserving water resources. It also helps to improve the livelihoods of people living in and around forests by providing employment opportunities in the forestry sector and by promoting sustainable agriculture.
However, there are also some challenges associated with the increase in forest cover in Bihar. One challenge is that it can lead to conflict between people and wildlife. Another challenge is that it can make it difficult to develop infrastructure in forested areas.
Despite these challenges, the increase in forest cover in Bihar is a positive development. It is important to continue to protect and manage forests in the state in order to ensure that they continue to provide a range of benefits to people and the environment.
The other options are incorrect because they do not represent the total recorded forest area of Bihar as per India State of Forest Report, 2017.
