Tick (✓) one box to identify which option is used to show the inputs and output of a Boolean expression. A flowchart □ B trace table □ C truth table □ D variable □

Choice C is correct because: In Boolean algebra and computer science, a truth table is a mathematical table used to determine and display all possible combinations of input values (typically \(0\) and \(1\), or FALSE and TRUE) alongside the resulting output of a Boolean expression or logic circuit. For \(n\) binary inputs, a truth table systematically lists all \(2^n\) possible input combinations in rows, with dedicated columns for the inputs and the corresponding final output, precisely fulfilling the definition given in the question. Choice A is incorrect because: A flowchart is a visual diagram that uses standardized geometric shapes (such as diamonds, rectangles, and parallelograms connected by directional arrows) to represent the flow of control and sequence of steps in an algorithm. It is not a tabular method specifically designed to display the comprehensive input-output relationships of a Boolean expression. Choice B is incorrect because: A trace table is a technique used in software development and testing to perform a manual "dry run" of an algorithm or program. It tracks how the values of variables change step-by-step as instructions are executed line-by-line to identify logic errors, rather than enumerating the functional outputs of a Boolean expression for all possible input combinations. Choice D is incorrect because: A variable is a named reference or storage location in computer memory that holds a single data value which can change during program execution. While a Boolean expression may contain variables as its operands, an individual variable itself cannot display the complete set of inputs and outputs of the expression.
