Consider the curve y = be^{-x/a} where a and b are non-zero real numbers. Then

Correct Answer is : xa+yb=1 is tangent to the curve where the curve crosses the axis of y

x/a+y/b=1 is tangent to the curve at (0, 0)

x/a+y/b=1 is tangent to the curve where the curve crosses the axis of y

x/a+y/b=1 is tangent to the curve at (a, 0)

x/a+y/b=1 is tangent to the curve at (2a, 0)
