Answers (1)

Answer:

 Option (a).

Hint:

 Simplify the given equation.

Given:

 2x-(1+\lambda )y+3\lambda z=0

Solution:

The given equation plane is,

2x-(1+\lambda )y+3\lambda z=0

We can rewrite the equation of the given plane as,

2x-(1+\lambda )y+3\lambda z=0

2x-y-\lambda (y-3z)=0

So, the given plane passes through the intersection of the planes

 2x-y=0 \text { and }y-3z=0.
