During the planning phase of a project, there is one activity for which duration and...

This question belongs to the Process domain because it deals with estimating methods and use of historical information. PMI’s current Lexicon defines analogous estimating as estimating duration, cost, or resources using historical data from a similar activity or project. PMI also notes that organizational process assets and lessons-learned repositories can include historical information from previous similar projects that helps support estimating.

Because the activity was performed previously in another company project, the best next step is to consult artifacts from that earlier project . Those records provide the closest available benchmark and allow the team to estimate based on real prior performance rather than guesswork. Option A is weaker because it relies only on opinion when better evidence exists. Option C is incorrect because deadline-driven reverse estimating is unreliable and can create unrealistic commitments. Option D is also inappropriate because the issue is estimation, not resourcing the work with a different team. PMP-style logic favors using historical data first when a comparable reference is available, making analogous estimating the strongest and most defensible approach.
