In a scheduling scenario, if task A takes 2 hours, task B takes 3 hours, and task C takes 1 hour, which of the following combinations allows for the earliest completion of all tasks if A must be done before B?
Step 1: Identify the tasks and their durations: Task A takes 2 hours, Task B takes 3 hours, and Task C takes 1 hour.
Step 2: Note the requirement that Task A must be completed before Task B.
Step 3: Consider the possible combinations of tasks while keeping the requirement in mind.
Step 4: Evaluate the combination C, A, B: First do Task C (1 hour), then Task A (2 hours), and finally Task B (3 hours).
Step 5: Calculate the total time for the combination C, A, B: 1 hour (C) + 2 hours (A) + 3 hours (B) = 6 hours.
Step 6: Check other combinations like A, C, B or A, B, C to see if they finish earlier, but they will take longer due to the requirement of A before B.
Step 7: Conclude that the combination C, A, B allows for the earliest completion of all tasks.
