D. \frac{(8)\cdot (-7)\cdot (6)}{(-4)\cdot (-2)\cdot (-3)} = \frac{-336}{-24} = 14

Por álgebra, recordamos los siguientes dos teoremas llamados teorema del signo para productos:

(-x)\cdot y = x\cdot (-y) = -x\cdot y, \forall \,x,y\in \mathbb{R} (1)

(-x)\cdot (-y) = x\cdot y, \forall \,x,y\in \mathbb{R} (2)

Basados en la información dada en la imagen y los teoremas descritos arriba, el producto del numerador debe ser negativo y el producto del numerador debe ser también negativo, más el resultado de la división debe ser positiva.

Por tanto, la opción D representa a la operación libre de errores.
