Which graph shows a dilation?

A
Image with description On a coordinate plane, the x and y axes ranges from negative 4 to positive 4 in increments of 1. 2 quadrilaterals are shown. The vertices of the larger quadrilateral are (negative 1 comma 0), (negative 3 comma 3), (1 comma 3), and (3 comma 0). The vertices of the smaller quadrilateral are (0 comma 0), (negative 1 comma 1), (1 comma 1), and (2 comma 0).
B
Image with description On a coordinate plane, the x and y axes range from negative 4 to positive 4 in increments of 1. 2 quadrilaterals are shown. The vertices of the larger quadrilateral are (negative 2 comma 0), (negative 4 comma 3), (0 comma 3), and (2 comma 0). The vertices of the smaller quadrilateral are (negative 1 point 5 comma 0), (negative 2 comma 2), (0 comma 2), and (0 point 5 comma 0).
C
Image with description On a coordinate plane, the x and y axes range from negative 5 to positive 5 in increments of 1. 2 quadrilaterals are shown. The vertices of the larger quadrilateral are (negative 2 comma 0), (negative 5 comma 3), (1 comma 3), and (4 comma 0). The vertices of the smaller quadrilateral are (negative 0 point 5 comma 0), (negative 1 comma 2), (1 comma 2), and (1 point 5 comma 0).
D
