Q. The Maxwell’s four equations are written as (i)$\oint\overrightarrow{\mathbf{E}}\mathbf{\ \bullet}\overrightarrow{\mathbf{ds}} = q/\varepsilon_{0}$ (ii)$\oint\overrightarrow{\mathbf{B}}\mathbf{\bullet}\overrightarrow{\mathbf{ds}} = 0$ (iii)$\oint\mathbf{E \bullet \ }\overrightarrow{\mathbf{dl}} = - \frac{d}{dt}\oint_{s}^{}{\overrightarrow{\mathbf{B}}\mathbf{\bullet}\overrightarrow{\mathbf{ds}}}$ (iv)$\oint\overrightarrow{\mathbf{B}}\mathbf{\bullet}\overrightarrow{\mathbf{dl}} = \mu_{0}I + \mu_{0}\varepsilon_{0}\frac{d}{dt}\oint_{s}^{}{\overrightarrow{\mathbf{E}}\mathbf{.\ }\overrightarrow{\mathbf{ds}}}$ The equation which have sources of $\overrightarrow{\mathbf{E}}$ and $\overrightarrow{\mathbf{B}}$ are
