A block of mass \( m \), lying on a smooth horizontal surface, is attached to a spring (of negligible mass) of spring constant \( k \). The other end of the spring is fixed, as shown in the figure. The block is initially at rest in its equilibrium position. If now the block is pulled with a constant force \( F \), the maximum speed of the block is

(a) \( \frac{F}{\pi \sqrt{m k}} \)
(b) \( \frac{\pi F}{\sqrt{m k}} \)
(c) \( \frac{F}{\sqrt{m k}} \)
(d) \( \frac{2 F}{\sqrt{m k}} \)
