答案：C
解析：
The probability that a point chosen from line A C will lie on line B C is the ratio of the length of line B C to the length of line A C. The length of line A B is 2x and the length of line B C is 3x, so the length of line A C is 5x. Therefore, the ratio of the length of line B C to the length of line A C is (3x)/(5x) = 3/5.
