Pressure is force per unit area, giving it dimensions of $\frac{ML}{T^2L^2} = \frac{M}{LT^2}$. To solve this, find what other quantity has the same $\frac{\text{mass}}{\text{length} \times \text{time}^2}$ structure—think about stress, energy density, or anything involving force spread over area or volume. Check each option by breaking it into mass, length, and time components.
