What are the shapes & hybridization of $SO_2$ & $SO_3$

$\begin{array}{1 1}(a)\;SO_2-Angular,sp^2,SO_3-trigonal\;planar,sp^2&(b)\;\;SO_3-Angular,sp^2,SO_3-trigonal\;planar,sp^2\\(c)\;SO_2-linear\;sp,SO_3-trigonal\;planar,sp^2&(d)\;SO_2-SP^3,pyramid,SO_3-sp^2,linear\end{array}$

Angular
Trigonal planar
$SO_3$-triangular planar,$Sp^2$
Hence (a) is the correct answer.
