Identify the true statement about the plane σ:2x+y2z+13=0 and the sphere κ:x2+y2+z22x2y4z+2=0.
Plane σ and sphere κ have no intersection at all.
Plane σ intersects sphere κ but does not pass through sphere’s center.
Plane σ is the tangent plane to sphere κ.
Plane σ intersects sphere κ and passes through sphere’s center.
