The vertices of ABC are A(2, 1), B(3, 4), and C(1, 3). If ABC is translated 1 unit down and 3 units to the left to create ADEF, what are the coordinates of the vertices of ADEF?
O A. D(-2,-2), E(0, 3), F(-1,0)
O B. D(-1,0), E(0, 3), F(-2, 2)
O
C. D(0, -1), E(0, 3), F(-2,-2)
o
D. D(0, 1), E(1, 2), F(1, 3)
