उत्तर
The equation of the plane passing through the intersection of the planes
ax + by + cz + d = 0
and lx + my + nz + p = 0
will be (ax + by + cz + d) + λ(lx + my + nz + p) = 0
x(a + λl) + y(b + λm) + z(c + λn) + (d + λp)=0 .......(1)
Since the plane is parallel to the line y=0 and z=0
a + λl=0
λ \[\frac{- a}{l}\]
putting the value of λ in equation (1), we get
Hence, option (a)
