Questions & Step-by-Step Solutions

If tasks A, B, and C must be completed in that order, which of the following is an invalid sequence?
  • Step 1: Understand that tasks A, B, and C must be completed in the order A, then B, then C.
  • Step 2: Identify what it means for a sequence to be valid. A valid sequence must follow the order of A before B and B before C.
  • Step 3: Look at the sequence B, A, C. Notice that B comes before A in this sequence.
  • Step 4: Since A must be completed before B, the sequence B, A, C does not follow the required order.
  • Step 5: Conclude that B, A, C is an invalid sequence because it breaks the rule of completing A before B.
