Answer: First option is correct.

Step-by-step explanation:

Since we have given that

[tex]r(x)=2-x^2\\\\w(x)=x-2[/tex]

we need to find the composition of function w and r i.e.

[tex]w\circ r=w(r(x))=w(2-x^2)=2-x^2-2=-x^2[/tex]

Since the range of  [tex]-x^2[/tex] must be [tex](-\infty,0}[/tex].

As its values can be any negative real number in this interval.

Hence, first option is correct.
