The correct option is B 3y+2z−4=0
Let P(α,β,γ) be the image of the point Q(3,5,7)=(x1,y1,z1) w.r.to the plane ax+by+cz+d=o=2x+y+z−3,
We know,
α−x1a=β−y1b=γ−z1c=−2ax1+by1+cz1+da2+b2+c2
α−32=β−51=γ−71=−22(3)+1(5)+1(7)−34+1+1=−2×156=−5
α=−7,β=0,γ=2
Image is P(−7,0,2)
Now required plane passes through P(−7,0,2) and contains the line x−1−1=y2=z−2−3
So plane passes through P(−7,0,2) and A(1,0,2)
D'R's of AP=(8,0,0)
∴ Plane equation is
∣∣
∣∣x−1yz−2800−12−3∣∣
∣∣=0⇒3y+2z−4=0
