Correct Answer: D
"When it comes to estimating the effort to complete the requirements on your Agile projects, there are three different “Sizing Units” that can be used:
Real Time, which is sometimes called Real Days or Actual Days. This refers to the actual time during each day that the team members are available and are productively working on specific Agile project tasks.
Ideal Time, or Ideal Days, where you make the assumption that your Agile project team members will have no interruptions in their work, such as checking email or attending meetings, and will be 100% productive every hour of every day.
Relative Size, which is the recommended “sizing unit” to use for requirements size estimation on your Agile project. This sizing unit allows you to estimate the “level of effort” a user story will take to complete, relative to the other user stories you will be performing on your Agile project.
Ideal Size is not a recognized sizing unit for estimating the level effort of effort to complete an Agile project requirement."
