A water pipe of length 5 m . and its ends are \( A \) and \( B \) it rests with its end \( A \) on a horizontal ground and one of its points \( D \) on a vertical fence of height 3 m . If the lower end \( A \) slide away from the fence at a rate \( \frac{5}{4} \mathrm{~m} / \mathrm{min} \)., then the rate of descending the end \( B \) when it reaches to the fence top \( =\mathrm{m} \)./min. \( \begin{array}{llll}\text { (a) } \frac{3}{5} & \text { (b) } \frac{3}{4} & \text { (C) } \frac{5}{4} & \text { (d) } \frac{4}{5}\end{array} \)
