Y = 1/4x + 1
-1/4x + y = 1
x - 4y = -4 <=====

y = -3/4x + 9
3/4x + y = 9
3x + 4y = 36 <=====

1/4x + 1 = -3/4x + 9
1/4x + 3/4x = 9 - 1
x = 8

y = 1/4x + 1
y = 1/4(8) + 1
y = 2 + 1
y = 3

solution is : (8,3)

and ur answer is : A

None of the others have any way to divide or multiply up to the area,
So yes, B.
