Calculate the work done to pull a block of mass $M$ by a constant force $F$ as shown in the figure. The coefficient of friction between the block and the ground is $\mu$.

• A
  $\frac{{\mu Mgd}}{{\cos \theta - \sin \theta }}$
• B
  $\frac{{Mgd}}{{\mu \cos \theta + \mu \sin \theta }}$
• C
  $\frac{{\mu Mgd}}{{\cos \theta + \mu \sin \theta }}$
• D
  $\frac{{{\mu ^2}Mgd}}{{\mu \cos \theta - \mu \sin \theta }}$
