A(n) _____ should have members who possess the skills and resources required to accomplish an undertaking successfully.​

A) ​single-session group
B) ​subgroup within a working group
C) ​task group with a specific purpose
D) ​open-ended group

A task group with a specific purpose is designed to achieve a goal or objective, and therefore requires members with specific skills and resources to successfully complete the task. A single-session group is not necessarily focused on accomplishing a specific task, while a subgroup within a working group and an open-ended group may not have such clear criteria for membership.
