Solution

The correct option is A Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1
Electric flux within any closed surface in region of uniform electric field is zero because the total number of electric lines of forces entering the closed surface equals that exiting the surface. Hence from Gauss theorem $(ϕ = \oint \to E .^n d s = \frac{Q_{e n}}{ϵ_{0}})$ the net charge enclosed within such a closed surface is zero.
