The correct answer is C. Both 1 and 2.

Statement 1 is correct because the total forest cover in the state is 15100 sq km.

Statement 2 is also correct because 15100 sq km is 29.73% of the state's geographical area.

To calculate the percentage of forest cover, we can use the following formula:

Percentage of forest cover = (Forest cover / Geographical area) * 100

In this case, the percentage of forest cover is:

(15100 sq km / 51000 sq km) * 100 = 29.73%

Therefore, both statements 1 and 2 are correct.
