Which of the following represent physical quantities represent the dimensional formula $\left[M^1{L}^{-2}{T}^{-2}\right]?$

$$\begin{gathered} Dimension of energy/area- \\ \left[Energy/Area\right]=\left[\frac{M{L}^2{T}^{-2}}{L^2}\right] \\ =\left[M{L}^{-2}\right] \\ Dimension \& pressure- \\ \left[Pressure\right]=\left[Force/Area\right] \\ =\left[\frac{ML{T}^{-2}}{L^2}\right] \\ =\left[M{L}^{-1}{T}^{-2}\right] \\ Dimension of force lengths- \\ \left[Force length\right] = \left[ML{T}^{-2}L\right] \\ =\left[M^1{L}^2{T}^{-2}\right] \\ Dimensionsofd pressure per unit length- \\ \left[Pressure per unit length\right]=\left[\frac{presssure}{length}\right] \\ =\left[\frac{M{L}^{-1}{T}^{-2}}{L}\right] \\ \left[M^1{L}^{-2}{T}^{-2}\right] \end{gathered}$$
