Which of the following is not an element of control logic?

• A. Next
• B. Input
• C. Output
• D. Sequence

Answer: (A)

Control logic is organized around how inputs drive decisions, the order in which operations occur, and what results are sent out. Inputs provide the information the logic uses to decide what to do next. Sequence describes the planned progression through tasks or states, ensuring operations happen in the correct order. Outputs are the signals the logic emits to actuators, displays, or other systems to perform actions. Next, however, isn’t a separate building block of control logic; it’s a way of describing the progression to the following step or state, determined by the sequencing rules. Because it isn’t an independent element, it’s the one that doesn’t belong as a fundamental component of control logic.
