Consider the following class definitions:Which of the following correctly sets the values of x and y?

A) void dClass: :setXY (int $a$ , int b)
{
bClass: : setx (a) ;
$y=b ;$
}
B) void dClass: setXY (int $a$ , int b)
{
$\mathrm{x}=\mathrm{a}$ ;
$y=b ;$
}
C) void dClass: setXY (int a, int b)
{
$x=$ bClass: : set $(a)$ ;
$y=$ bClass: : setY (b) ;
}
D) void dClass: setXY (int a, int b)
{
$x=$ bClass.setx (a) ;
$\mathrm{b}=\mathrm{y} ;$
}
