\text { Torque }=\text { F.S. } & =\left[\mathrm{MLT}^{-2}\right][\mathrm{L}] \\
& =\left[\mathrm{ML}^2 \mathrm{~T}^{-2}\right]
\end{aligned}
$$
correct option is (3)
(2) Angular moment $=$ M.I. $\times$ angular velocity
$$
\begin{aligned}
=\left[\mathrm{ML}^2\right]\left[\mathrm{T}^{-1}\right] & =\left[\mathrm{ML}^2 \mathrm{~T}^{-1}\right] \\
\text { Work }=F . S . & =\left[\mathrm{MLT}^{-2}\right][\mathrm{L}] \\
& =\left[\mathrm{ML}^2 \mathrm{~T}^{-2}\right]
\end{aligned}
$$
(3) Work $=\left[\mathrm{ML}^2 \mathrm{~T}^{-2}\right]$ from
