NEET 2022, Physics Q16: Units And Dimensions

Magnetic permeability ${\mu }_0$ has SI units of ${\text{N/A}}^2=\text{kg}\cdot \text{m}\cdot {\text{s}}^{-2}\cdot {\text{A}}^{-2}$.

Translating to dimensional form: $[{\mu }_0]=[{\text{MLT}}^{-2}{\text{A}}^{-2}]$.

This matches the given dimensions, so the answer is magnetic permeability.
