Answer :
For x = (-2)
[tex]:\implies\sf\:3^x[/tex]
[tex]:\implies\sf\:3^{-2}[/tex]
[tex]:\implies\sf\:\dfrac{1}{3^2}\:\longrightarrow\:m^{-n}=\dfrac{1}{m^n}[/tex]
[tex]:\implies\boxed{\bf{\dfrac{1}{9}}}[/tex]
For x = 1
[tex]:\implies\sf\:3^x[/tex]
[tex]:\implies\sf\:3^1[/tex]
[tex]:\implies\boxed{\bf{3}}[/tex]
For x = 3
[tex]:\implies\sf\:3^x[/tex]
[tex]:\implies\sf\:3^3[/tex]
[tex]:\implies\boxed{\bf{27}}[/tex]
Hence, Option-B is correct.
