A man is walking on a straight line. The arithmetic mean of the reciprocals of the intercepts of this line on the coordinate axis is \( \frac{1}{4} \). Three stones, \( A, B \) and \( C \) are placed at the point \( (1,1),(2,2) \) and \( (4,4) \) respectively. Then which of these stones is/are on the path of the man
(a) \( B \) only
(b) \( A \) only
(c) All of three
(d) C only
