The inward and outward electric flux for a closed surface in units of \[N-{{m}^{2}}/C\]are respectively \[8\times {{10}^{3}}\] and \[4\times {{10}^{3}}.\] Then the total charge inside the surface is [where \[{{\varepsilon }_{0}}\]= permittivity constant]

• A. \[4\times {{10}^{3}}C\]
• B. \[3.14\,\,N{{m}^{2}}/C\]
• C. \[\frac{(-\,4\times {{10}^{3}})}{\varepsilon }C\]
• D. \[-\,4\times {{10}^{3}}{{\varepsilon }_{0}}C\]
