A block of mass \( \mathrm{m} \) lying on a rough horizontal plane is acted upon by a horizontal force \( P \) and another force \( Q \) inclined an at angle \( \theta \) to the vertical. The minimum value of coefficient of friction between the block and the surface for which the block will remain in equilibrium is:
(a) \( \frac{P+Q \sin \theta}{m g+Q \cos \theta} \)
(b) \( \frac{P \cos \theta+Q}{m g-Q \sin \theta} \)
(c) \( \frac{P+Q \cos \theta}{m g+Q \sin \theta} \)
(d) \( \frac{P \sin \theta-Q}{m g-Q \cos \theta} \)
