Answer: (ii) RISC

Explanation:

  • RISC (Reduced Instruction Set Computer): Aimed at reducing CPI / execution time per instruction via simple, fixed-length instructions, load/store architecture, hardwired control, pipelining - executes each instruction in ~1 cycle.
  • CISC (Complex Instruction Set Computer): Aimed at reducing number of instructions/code size via complex variable-length instructions, microprogrammed control - but each instruction takes multiple cycles.
  • ISA = Instruction Set Architecture (interface), ANNA = not relevant.

Hence architecture focused on time of execution = RISC.
