* A is correct because Planning poker is an estimation technique that you can use in an Agile delivery approach to size the user stories during sprint planning. Planning poker is a game where each team member uses a set of cards with numbers that represent the relative effort of a user story. The team members reveal their cards simultaneously and discuss their estimates until they reach a consensus.
