-$x y + y + 3 x + 3$
A) $( x + 1 ) ( 3 y + 3 )$
B) $( x + 1 ) ( y + 3 )$
C) $( 3 x + 3 ) ( y + 1 )$
D) $( x + 3 ) ( y + 1 )$

By grouping $xy + y$ and $3x + 3$, we can factor out a $y$ from the first group and a $3$ from the second, resulting in $y(x + 1) + 3(x + 1)$. This can be further factored into $(x + 1)(y + 3)$.
