Find the Opposite (Additive Inverse), and the Reciprocal (Multiplicative Inverse) $\frac { 1 } { \mathrm {~m} }$

Find the opposite (additive inverse) , and the reciprocal (multiplicative inverse) . Assume that the value of an expression is
not 0.
-Expression: -m Opposite:----Reciprocal:----

A) Opposite: $\frac { 1 } { \mathrm {~m} }$
Reciprocal: m

B) Opposite: $m$
Reciprocal: $\frac { 1 } { \mathrm {~m} }$

C) Opposite: $- \frac { 1 } { m }$
Reciprocal: m

D) Opposite: m
Reciprocal: $- \frac { 1 } { \mathrm {~m} }$
