Best answer
Right choice is (a) Dual reflector antenna

For explanation: Usually a feed forward is used in reflector antenna and feed antenna is placed at focus of the reflector. When a sub-reflector is placed at the focus along with the feed antenna it is called dual reflector antenna. Example of dual reflector antenna: Cassegrain antenna.

Convex-Convex is a lens antenna.
