Best answer
Right choice is (c) DSP

Explanation: Digital signal processors are simple to program, cost-effective, and power-efficient when compared to other devices such as ASIC and FGPA. However small memory and complicated instruction set architecture can increase the re-programmability cost of a digital signal processor.
