Find $\sin B$ and $\tan B$ .

A) $\sin \mathrm { A } = \frac { \mathrm { b } } { \mathrm { c } } ; \tan \mathrm { A } = \frac { \mathrm { b } } { \mathrm { a } }$
B) $\sin \mathrm { A } = \frac { \mathrm { c } } { \mathrm { b } } ; \tan \mathrm { A } = \frac { \mathrm { b } } { \mathrm { a } }$
C) $\sin A = \frac { c } { a } ; \tan A = \frac { b } { a }$
D) $\sin \mathrm { A } = \frac { \mathrm { a } } { \mathrm { c } } ; \tan \mathrm { A } = \frac { \mathrm { a } } { \mathrm { b } }$
