Best answer
Right option is (b) analog circuit and reverse engineering

The explanation is: RF MEMS allows the selection of switches from a collection of analog circuit and components. This is the direct implementation of MEMS in the design. Reengineering and selection of analog circuits are according to the programmability requirements of software defined radio.
