Q: If the there were only type of charge in the universe, then
(a) $\oint_{s} \vec{E}.{dS} \ne 0 $ on any Surface
(b) $\oint_{s} \vec{E}.{dS} = 0 $ if the charge is outside the surface
(c) $\oint_{s} \vec{E}.{dS} $ could not be defined
(d) $\oint_{s} \vec{E}.{dS} = \frac{q}{\epsilon_0} $ if charges of magnitude q were inside the surface
Ans: (c) & (d)
