Electric Flux & Gauss's Law

A point charge $+q$ is placed at the centre of a cube of side $l$ . The electric flux emerging from the cube is

Show answer and solution

Answer: (d)

The charge is fully enclosed by the cube.
Gauss's law: $\phi = \dfrac{q}{\varepsilon_0}$ , independent of $l$ .
So the answer is (d).
