Out of the four figures that follow,you are to indicate which figure will best represent the relationship amongst the three classes: Women,Mothers,Widows.

(C) $1$. All mothers are women,so the set of 'Mothers' is a subset of the set of 'Women'.
$2$. Some mothers can be widows,and some women who are not mothers can also be widows.
$3$. Therefore,the circle representing 'Widows' will intersect both the 'Women' circle and the 'Mothers' circle.
$4$. The most accurate representation is a large circle for 'Women',a smaller circle for 'Mothers' inside it,and a third circle for 'Widows' that overlaps with both.
