Let y=y(x), y 0, be solution curve of differential equation (1+x^2)dy=y(x-y)dx. If y(0)=1 & y(2√2)=b

Let y=y(x), y greater than 0, be a solution curve of differential equation (1+x^2)dy=y(x-y)dx.
If y(0)=1 and y(2√2)=b, then:
A. e^b^-1=e^-2(3+2√2)
B. e^3b^-1=e(5+√2)
C. e^3b^-1=e(3+2√2)
D. e^b^-1=e^-2(5+√2).
