Right answer is (a) Orange peel antenna

To elaborate: Orange peel antenna is one of the types of parabolic antenna with its shape in form of letter C. It is mainly used in the search radars. Pill box antenna gives wide and narrow beams in different planes. Yagi-Uda antenna is formed with the help of dipoles and reflectors placed at some distances to get a unidirectional beam with good directivity.
