Correct answer: B

The solar constant is defined as the solar energy received per unit area per unit time.

So,

\text{Solar constant} = \frac{\text{Energy}}{\text{Area} \times \text{Time}}

[E] = ML^2T^{-2}

[A] = L^2

[T] = T

[\text{Solar constant}] = \frac{ML^2T^{-2}}{L^2 \cdot T}

= M L^{2-2} T^{-2-1}

= ML^0T^{-3}

The correct dimension is:

ML^0T^{-3}

So the correct option is B.
