Answer: A

Explanation:

An estimate is not the same as a commitment. Distractions and availability should not be part of the estimate, they can be forecasted from the capability and past performance. Testing should be considered as part of the development estimate according to the Definition of Done. Although usually Agile Teams, prefers other methods, estimate in hours is not forbidden. The Developers who will be doing the work are responsible for the sizing, they decide the method that is useful for them. Therefore, they have to be transparent and open with what they think and with the actual work that is needed without considering distractions or inflating the estimate.
