Mark the correct alternative in the following:
The plane 2x – (1 + λ)y + 3λz = 0 passes through the intersection of the planes.
The given equation plane is, 
We can rewrite the equation of the given plane as,
2x–(1 + λ)y + 3λz=0
2x - y - λ(y - 3z)=0
So, the given plane passes through the intersection of
the planes 2x - y=0 and y - 3z=0.
