In a set of tasks where A must be completed before D, and D must be completed before E, which of the following is a valid order?

In a set of tasks where A must be completed before D, and D must be completed before E, which of the following is a valid order?

Step 1: Identify the tasks involved: A, D, and E.
Step 2: Understand the constraints: A must be completed before D, and D must be completed before E.
Step 3: Write down the order of tasks based on the constraints.
Step 4: Start with A, since it must come first.
Step 5: Next, write D after A, because A must be completed before D.
Step 6: Finally, write E after D, since D must be completed before E.
Step 7: The valid order is A, D, E, which follows all the constraints.
