A block (mass $=M kg$ ) is placed on a rough inclined plane. A force $F$ is applied parallel to the inclined (as shown in figure) such that it just starts moving upward. The value of $F$ is
  • A$M g \sin \theta-\mu M g \cos \theta$
  • B$M g \sin \theta+\mu M g \cos \theta$
  • C$M g \sin \theta$
  • D$\mu M g \cos \theta$
