In a set of tasks where A must be completed before B, and C must be completed before A, which of the following sequences is valid?

In a set of tasks where A must be completed before B, and C must be completed before A, which of the following sequences is valid?

Step 1: Identify the tasks and their dependencies. We have three tasks: A, B, and C.
Step 2: Understand the dependencies: A must be completed before B, and C must be completed before A.
Step 3: Write down the order of tasks based on the dependencies. Since C must be done first, it goes first in the sequence.
Step 4: After C, A must be completed next because A cannot be done before C.
Step 5: Finally, B can be completed after A since A must be done before B.
Step 6: The valid sequence is C, A, B, which respects all the dependencies.
