Coplanar: Lines are said to be coplanar if they lie in the same plane.If the two lines \(\rm {x -x_1\over a}={y-y_1\over b}={z-z_1\over c}\) and \(\rm {x -x_2\over p}={y-y_2\over q}={z-z_2\over r}\) are coplanar, then
\(\begin{vmatrix} x_2-x_1& y_2-y_1 & z_2-z_1\\ a& b &c \\ p& q &r \end{vmatrix} = 0\)
∴ Option 2 is correct
