An electric field given by $\overrightarrow{\mathrm{E}}=4\widehat{\mathrm{i}}+3\left({\mathrm{y}}^2+2\right)\widehat{\mathrm{j}}$ pierces Gaussian cube of side 1 m placed at origin such that its three sides represents x, y and z axes. The net charge enclosed within the cube is

• A

  $4{\mathrm{\epsilon }}_{\mathrm{o}}$

• B

  $3{\mathrm{\epsilon }}_{\mathrm{o}}$

• C

  $5{\mathrm{\epsilon }}_{\mathrm{o}}$

• D

  Zero
