We know that T is the project leader and W is a project member.
L: T M: W M: _
The remaining workers who could possibly be the final project member are Q, R, S, V, and X.
Rule 1 tells us that Q and R can only be project members if they are leading the project. As T is the project leader, Q and R cannot be on the project.
Rule 3 tells us that if W is a project member, then neither R nor V can be a project member. As W is a project member, V cannot be on the project. Remember that we have already eliminated R based on Rule 1.
Therefore, the only possible remaining project members are S and X. This is restated by answer choice (D), making it the correct answer.
Hope this helps! Please let us know if you have any further questions.
