(b) Motorola

(c) AMD

(d) Intel and Motorola

I have been asked this question in a dream while sleeping

The doubt is from Hybrid Architecture -RISC and CISC Convergence, Advantages of RISC, Design Issues of RISC Processors -2 in portion RISC Architecture of Microprocessor

Answer 1

The correct option is (d) Intel and Motorola

For explanation I would say: In RISC, each instruction is of the same length, so that it may be fetched in a single operation. The traditional microprocessors from Intel or Motorola support variable length instructions.
