Pick up the correct statement from the following :

• When the electric field oscillates in the direction of the electric vector, a plane polarised wave is formed.
• When the electric vector is in the plane of incidence, vertical polarisation is formed.
• When the electric vector is at right angles to the plane of incidence, horizontal polarization wave is formed.
• The plane containing the incident ray and normal to the reflecting surface at the point of incidence is called the plane of incidence.
• All of these
