The Work Breakdown Structure (WBS) is a hierarchical decomposition of the project deliverables and work into smaller and more manageable components. One of the key activities during the development of the WBS is to estimate the time and cost required for each activity.

To determine the most appropriate resource to provide the estimates, we need to consider who has the necessary knowledge and expertise. Here are the four options provided in the question and an explanation of their suitability:

A. Project team members: The project team members are the individuals responsible for performing the work activities in the project. They have firsthand experience and knowledge about the tasks they are responsible for and may be able to provide useful input regarding time and cost estimates. However, their estimates may be biased, optimistic, or pessimistic, and they may not have the necessary experience or knowledge to provide accurate estimates for other activities in the project.

B. Project sponsor: The project sponsor is the individual or group that provides the financial resources, approves changes, and generally supports the project. While the project sponsor may have a broad understanding of the project's goals, they may not have the necessary knowledge or expertise to provide accurate time and cost estimates.

C. Project manager: The project manager is responsible for overseeing the project and ensuring that it is completed within scope, time, and budget constraints. They have a broad understanding of the project's goals and requirements, as well as knowledge and expertise in project management. The project manager is the most appropriate resource to provide accurate time and cost estimates for the project activities.

D. Project scheduler: The project scheduler is responsible for creating and managing the project schedule. They have a detailed understanding of the project's activities and dependencies and can provide input regarding time estimates. However, they may not have the necessary knowledge or expertise to provide accurate cost estimates.

Therefore, the most appropriate resource to provide cost and time estimates for the project activities is the project manager (option C). They have a broad understanding of the project's goals and requirements, as well as knowledge and expertise in project management, making them the best-suited resource to provide accurate estimates.
