Question 1
Four team members (David, Eva, Charlie, Alice) must be assigned to four unique tasks (Testing, Design, Documentation, Deployment). The assignments must follow these rules:
1. David must handle Testing.
2. Eva cannot handle Deployment.
3. Charlie and Alice must be adjacent in (Testing → Design → Documentation → Deployment).
Based on the constraints, which statement MUST be true?
No valid schedule found given the constraints. The only guaranteed assignment is: David must handle Testing.
If the constraints cannot all be satisfied, fallback is to force rule 1's assignment.
If the constraints cannot all be satisfied, fallback is to force rule 1's assignment.
