Multiple Choice

Gauss' Law for magnetism is

A) $\oint \overrightarrow { \mathrm { B } } \cdot \mathrm { d } \overrightarrow { \mathrm { S } }$ = 0, only if no magnets are inside the surface.
B) $\oint \overrightarrow { \mathrm { B } } \cdot \mathrm { d } \overrightarrow { \mathrm { l } }$ = 0, only if no magnets are inside the loop.
C) $\oint \overrightarrow { \mathrm { B } } \cdot \mathrm { d } \overrightarrow { \mathrm { S } }$ = 0.
D) $\oint \overrightarrow { \mathrm { B } } \cdot \mathrm { d } \overrightarrow { \mathrm { l } }$ = 0.
