Find the dimension of physical quantity $X$ in the equation $Force=\large\frac{X}{Density}$

\[(a)\;M^1L^4T^{-2}\quad (b)\;M^2L^{-2}T^{-1} \quad (c)\;M^2L^{-2}T^{-2}\quad (d)\;M^1L^{-2}T^{-1}\]

Can you answer this question?

$X=Force \times Density$
$\quad=MLT^{-2} \large\frac{M}{L^3}$
$\quad=M^2L^{-2}T^{-2} $
$x=M^2L^{-2}T^{-2}$
Hence c is the correct answer.
