Which of the following Maxwell's equation is valid for time varying conditions but not valid for static conditions :

Question

$\oint \overrightarrow{\mathrm{E}} \cdot \overrightarrow{d l}=0$

$\oint \vec{B} \cdot \overrightarrow{d l}=\mu_{0} I$

$\oint \vec{E} \cdot \overrightarrow{d l}=-\frac{\partial \phi_{B}}{\partial t}$

$\oint \vec{D} \cdot \overrightarrow{d A}=Q$
