Choose the correct answer from the options given below :

Accepted Answer

Gauss's law $\oint \vec{E} \cdot \overrightarrow{d s}=\frac{q}{\epsilon_{0}} \quad(\mathrm{~A} ightarrow \mathrm{IV})$
Faraday's law $\oint \vec{E} \cdot \overrightarrow{d l}=-\frac{d \phi_{B}}{d t} \quad(\mathrm{~B} ightarrow \mathrm{I})$
Gauss's law in magnetism $\oint \vec{B} \cdot \overrightarrow{d A}=0 \quad(\mathrm{C} ightarrow \mathrm{II})$
Ampere's-Maxwell law $\oint \vec{B} \cdot \overrightarrow{d l}=\mu_{0} i_{c}+\mu_{0} \in_{0} \frac{d \phi_{E}}{d t}$
