Which of the following molecule has minimum % s-character in it's hybrid orbital for the underlined atom?

The molecule which has maximum % s-character in it's hybrid orbital for the underlined atom is,
$H_{2}C=CH-C{H}_3$
Here,
 (a) ${\mathrm{XeO}}_{4}s{p}^3(\mathrm{\%}s=25)$
(b) ${\mathrm{XeO}}_2{\mathrm{F}}_{4}s{p}^3{d}^2(\mathrm{\%}s=16)$
(c) ${\mathrm{H}}_3{\mathrm{PO}}_{4}s{p}^3(\mathrm{\%}s=25)$
Thus, the molecule which has minimum % s-character in it's hybrid orbital for the underlined atom is ${\mathrm{XeO}}_2{\mathrm{F}}_4$.

Hence, correct option is B.
