Why does the agile approach plan the work continuously throughout the project?

A. Agile methods break down the work into small chunks so the team can complete one iteration at a time.

B. An agile product owner can't know what they really need until they see a prototype in action.

C. Agile teams are asked to prioritize tasks that deliver value, rather than spending their time planning.

D. Agile projects are subject to uncertainty and high rates of change that make upfront planning inefficient.
