Answer»

Right option is (b) 80486

To explain: 80486 have a five stage pipeline ALU. These include FETCH, DECODE, execute, MEMORY access and WRITE back. This helps in accessing instruction faster and thus makes the PROCESSOR faster. 80386DX have a three-stage pipelining which only includes fetch, decode and execute.
