we are given


(y^2)/(y-3)*(y^2-y-6)/(y^2+1y)

we know that denominators can not be zero

so, restrictions would be values of y where denominator is not zero


y-3\\eq 0


y\\eq 3


y^2+1y \\eq 0


y(y+1) \\eq 0


y \\eq 0


y \\eq -1

so, restrictions are


y \\eq 0


y \\eq -1


y\\eq 3


(y^2)/(y-3)*(y^2-y-6)/(y^2+1y)

now, we can factor numerators and denominator

and then we can simplify it


(y^2)/(y-3)*(y^2-y-6)/(y^2+1y)=(y^2)/(y-3)*((y-3)(y+2))/(y(y+1))

now, we can cancel it


(y^2)/(y-3)*(y^2-y-6)/(y^2+1y)=(y(y+2))/(y+1)


(y^2)/(y-3)*(y^2-y-6)/(y^2+1y)=(y^2+2y)/(y+1)

so,

option-B..........Answer
