To simplify the given expression, we first find a common denominator for the fractions in the numerator and the denominator. The common denominator for both $\frac{1}{m}$ and $\frac{1}{z}$ is $mz$. Thus, the expression becomes $\frac{\frac{z+m}{mz}}{\frac{z-m}{mz}}$. Simplifying this, we get $\frac{z+m}{z-m}$, which matches option B.

Simplify - 1m+1z1m−1z\frac { \frac { 1 } { m } + \frac { 1 } { z } } { \frac { 1 } { m } - \frac { 1 } { z } }m1​−z1​m1​+z1​​

Simplify
- $\frac { \frac { 1 } { m } + \frac { 1 } { z } } { \frac { 1 } { m } - \frac { 1 } { z } }$
