A project manager is analyzing a table of tasks for an upcoming software release. The table includes 'Task ID', 'Estimated Hours', 'Dependency (Task ID)', and 'Assigned Developer'. Tasks must be completed in order of their dependencies. If Task 101 has no dependency, Task 102 depends on Task 101, and Task 103 depends on Task 102, which of the following statements must be true if Task 101 has an 'Estimated Hours' of 8 and 'Assigned Developer' is 'Alice'?

A Task 102 cannot start until Alice completes her work on Task 101.
B Task 103 can be assigned to a different developer simultaneously with Task 102.
C The total estimated hours for all three tasks cannot exceed 24 hours.
D If Task 101 is delayed, Task 103 will necessarily be completed by a different developer.

✓ Correct Answer: Option A

Dependencies mean a subsequent task cannot begin until its prerequisite is complete. If Task 102 depends on Task 101, then Task 102 cannot start until Task 101, assigned to Alice, is finished.
