Triangle CAT is an isosceles triangle with vertices (2, 1), (6, 1), and (4, 7). Triangle DOG is similar to triangle CAT, and two of its vertices are (3, –1) and (5, –1). If the third vertex has a y-coordinate that is less than –1, what are the coordinates of the third vertex?
A. (3, -4)
B. (3, -5)
C. (4, -4)
D. (4, -5)
