The Maxwell's four equations are written as: $\int {\vec{E}.\vec{dS}} = \frac{q}{\epsilon_0}$ $\int {\vec{B}.\vec{dS}} = 0$ $\int {\vec{E}.\vec{dl}} = \frac{d}{dt} \int{\vec{B}.\vec{dS}}$ $\int {\vec{B}.\vec{dl}} = \mu_0 \epsilon_0 \frac{d}{dt} \int{\vec{E}.\vec{dS}}$

Out of the above four equations which do not contain source field are:

(i) and(ii)            (ii)only (iii) only All of Four

(ii)only
