Q9. The translational degrees of freedom ( $f _ { t }$ ) and rotational degrees of freedom ( $f _ { r }$ ) of $\mathrm { CH } _ { 4 }$ molecule are:\\
(1) $f _ { t } = 2$ and $f _ { r } = 2$\\
(2) $f _ { t } = 3$ and $f _ { r } = 3$\\
(3) $f _ { t } = 3$ and $f _ { r } = 2$\\
(4) $f _ { t } = 2$ and $f _ { r } = 3$
