Which of the following cannot be the direction ratios of the straight line $\frac{x-3}{2}=\frac{2-y}{3}=\frac{z+4}{-1}$?

$2,3,-1$

The correct answer is Option (3) → $2,3,-1$

converting line to std. form

$\frac{x-3}{2}=\frac{2-y}{3}=\frac{z+4}{-1}$

direction ratios should be $λ(2,-3,-1)$

where $λ$ is always constant

so $(2,-3,-1)$ can't be direction ration
