Which Process Group and Knowledge Area include the Sequence Activities process?

In accordance with the PMBOK® Guide (Process Groups and Knowledge Areas Mapping), the Sequence Activities process is the process of identifying and documenting relationships among the project activities.

Knowledge Area: This process belongs to Project Schedule Management (referred to as Project Time Management in earlier versions of the PMBOK® Guide). It focuses on the logical sequencing of work to achieve the greatest efficiency given all project constraints.

Process Group: It is a critical component of the Planning Process Group. After the activities are defined (in the Define Activities process), they must be sequenced using logical relationships (Finish-to-Start, Start-to-Start, etc.) to create a network diagram, which eventually leads to the development of the project schedule.

Key Purpose: The primary benefit of this process is that it defines the logical sequence of work to achieve the greatest efficiency given all project constraints.

Analysis of Distractors:

A and B (Executing Process Group): The Executing Process Group involves carrying out the work defined in the project management plan. Sequencing is a foundational planning activity that must occur before execution begins.

B and D (Project Cost Management): Project Cost Management is concerned with budgeting, estimating, and controlling costs (e.g., Determine Budget, Control Costs). While the sequence of activities affects the cash flow, the process itself is a function of schedule (Time) management.
