Here we need to put the values of x ,y from the given option to the given equ. $$y=\frac{x^2}{x+1}$$

only option B and D satisfy the equa.

Considering option B

x= -2 and y =-4

we have $$-4$$ = $$\frac{(-2)^2}{(-2+1)}$$=$$-4$$

and in option D
x= 1 , y =1/2

therefore $$\frac{1}{2}$$= $$\frac{(1)^2}{(1+1)}$$=$$\frac{1}{2}$$
