CSe2 has Lewis structure like this: Se=C=Se (here are valence e- around the Se too, but no need to worry about these), Since it is considered that there are 2 bonds the shape would be linear. Linear corresponds to "sp" hybridization
H2Se is a bent molecule with a bond angle of 91 0. The hybridisation is usually taught as being sp3, but this is incorrect. The bond angle suggests virtually no hybridiation as it so close to 90 0 which is the angle between p orbitals,

The answer is SeF6.This is figured by:2.231 grams of Se divided by 78.79 g/mol = 0.0283 moles of Se3.221 grams of F divided by 18.998 g/mol = 0.1695 moles of F0.1695 moles of Se/0.0283 moles of F = 5.9909 ~ 6 moles of Se/mole of FSo SeF6

This breeding method is called hybridization. It is possible only in those cases where sexual barrier of crossing does not exist.
The Se (selenium) would be sp3d hybridized.

Selenium fluorides are: SeF2, Se2F2, SeF4, SeF6.
The hybridization is sp3d.
