A wave going a solid

Choose the correct option: (i) A surface on which the wave disturbance in same phase at all points is called a wavefront. (ii) The direction of a wave at a point is perpendicular to the wavefront through that point. (iii) The wavefronts of a wave originating from a point source is spherical. The wavefronts for a wave going along a fixed direction are planes perpendicular to that direction.
