Identify the true statement about the plane ρ:x+y−z+1=0 and the sphere κ:x2+y2+z2−2x+4y−6z+11=0.
Plane ρ is the tangent plane to sphere κ.
Plane ρ intersects sphere κ and passes through sphere’s center.
Plane ρ and sphere κ have no intersection at all.
Plane ρ intersects sphere κ but does not pass through sphere’s center.
