Select the correct option:
A
$-\frac{F}{m} \cos \theta-\mu_k\left(g-\frac{F}{m} \sin \theta\right)$
B
$\frac{F}{m} \cos \theta-\mu_k\left(g-\frac{F}{m} \sin \theta\right)$
C
$\frac{F}{m} \cos \theta-\mu_k\left(g+\frac{F}{m} \sin \theta\right)$
D
$\frac{F}{m} \cos \theta+\mu_K\left(g-\frac{F}{m} \sin \theta\right)$
