Let $A$ be the set of persons who live in Fresno area and $B$ be the set of men live the same area. A relation $f$:AlongrightarrowB is defined as "Assign a person $y$ in $B$ to a person $x$ in $A$ if $y$ is the father of $x"$

Then the inverse of this relation $f^{-1}$:BlongrightarrowA can be defined as

A$.$ Assign a person $y$ in $A$ to a person $x$ in $B$ if $x$ is a son of $y$

B$.$ Assign a person $y$ in $A$ to a person $x$ in $B$ if $x$ is the father of $y$

C$.$ Assign a person $y$ in $B$ to a person $x$ in A such that $x$ is the father of $y$

D$.$ Assign a person $y$ in $B$ to a person $x$ in $A$ if $y$ is a son of $x$
