Show answer & explanation
Correct answer: A
Answer: Both Statement I and Statement II are true
Explanation:
Statement I: CISC architectures provide many addressing modes (for example, immediate, direct, indirect, indexed, base-plus-offset), which support complex instructions and flexible operand access.
Statement II: RISC architectures follow a load/store model where only explicit load and store instructions access memory; all other instructions operate on registers. This simplifies instruction design and improves pipelining.
Therefore both statements are correct.
