The performance of a pipelined processor suffers if :
(A) the pipeline stages have different delays
(B) consecutive instructions are dependent on each other
(C) the pipeline stages share hardware resources
(D) all of the above


Answer: (D)

Explanation: Pipelining is a method to execute a program breaking it in several independent sequence of stages.

In that case pipeline stages can’t have different delays ,no dependency among consecutive  instructions and sharing of hardware resources should not be there.

So option (D) is correct
