  4. D \(3\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(2\)

Step-by-step Solution

Detailed explanation

Theequation of anyplane passing through given line is \((x+y+2 z-3)+\lambda(2 x+3 y+4 z-4)=0\) \(\Rightarrow(1+2 \lambda) x+(1+3 \lambda) y+(2+4 \lambda) z-(3+4 \lambda)=0\) If this plane is parallel to z-axis then normal to the plane will be perpendicular to z-axis.…
