The equation of straight line passing through the points (a, b, c) and (a ? b, b? c, c ? a), is [MP PET 1994]

\[\frac{x-a}{a}=\frac{y-b}{b}=\frac{z-c}{c}\]

\[\frac{x-a}{a-b}=\frac{y-b}{b-c}=\frac{z-c}{c-a}\]

\[\frac{x-a}{b}=\frac{y-b}{c}=\frac{z-c}{a}\]

\[\frac{x-a}{2a-b}=\frac{y-b}{2b-c}=\frac{z-c}{2c-a}\]
