The Maxwell's four equations are written as:

$\int {\vec{E}.\vec{dS}} = \frac{q}{\epsilon_0}$

$\int {\vec{B}.\vec{dS}} = 0$

$\int {\vec{E}.\vec{dl}} = \frac{d}{dt} \int{\vec{B}.\vec{dS}}$

$\int {\vec{B}.\vec{dl}} = \mu_0 \epsilon_0 \frac{d}{dt} \int{\vec{E}.\vec{dS}}$

The equations which have sources of $ \vec{E} \text { and } \vec{B}$ are  

(i) and(iv)
