Explanation
Wide Band Delphi (including Planning Poker) is a consensus-based estimating technique where team members independently select their estimates, reveal them simultaneously, and then discuss the reasoning behind differing estimates. This process repeats until the team converges on a shared estimate. The simultaneous reveal prevents anchoring bias. Option B describes analogous estimating. Option C partially describes relative sizing but not the Delphi discussion/consensus process. Option D describes a variation of three-point (PERT) estimating, not Delphi.
