As shown in the figure, use the benchmark BE to measure the height of the tree CD. EB and DC are perpendicular to AC, If the length of the benchmark BE is 2.0, AB = 3.0, AC = 9.0, and the points A, E, and D are on a straight line, then the tree CD is ()
Choices:
A:6米
B:7.5米
C:8米
D:8.5米
Please directly answer the question and provide the correct option letter, e.g., A, B, C, D.
