NEET UG PHYSICS MCQ: UNITS & MEASUREMENTS

Option D ([$\mathrm{M}{\mathrm{L}^2}{\mathrm{T}^{ - 2}}{\mathrm{A}^{ - 1}}$]) is correct because magnetic flux is given by $\phi = B \cdot A$, where B is the magnetic field and A is the area. The dimension of B is [MT^-2A^-1] and the dimension of A is [L²], so the dimension of magnetic flux is [ML²T^-2A^-1].
