The correct answer is:
$\left[\mathrm{ML}^2 \mathrm{~T}^{-2}\right]$
Dimension of torque
$\begin{aligned}
\tau & =\mathrm{F} \times \mathrm{r}=\left[\mathrm{MLT}^{-2}\right][\mathrm{L}] \\
& =\left[\mathrm{ML}^2 \mathrm{~T}^{-2}\right]
\end{aligned}$
$\begin{aligned}
\tau & =\mathrm{F} \times \mathrm{r}=\left[\mathrm{MLT}^{-2}\right][\mathrm{L}] \\
& =\left[\mathrm{ML}^2 \mathrm{~T}^{-2}\right]
\end{aligned}$
