Which inputs lead to a TRUE output in a Boolean expression?

In Boolean expressions, the output is determined based on the logical values of the inputs. True inputs lead to a TRUE output because in logic, the value of TRUE is often associated with the fulfillment of a condition or the validity of an expression.

When the expression contains at least one TRUE input in scenarios like the logical OR operation, the overall output is TRUE. Even in circumstances where AND operations are used, if all the operands are TRUE, the result remains TRUE. This constant adherence to the logical state of TRUE demonstrates that providing TRUE inputs is essential to yielding a TRUE output.

The other choices describe various types of inputs or conditions, but they do not guarantee a TRUE outcome: False Inputs will produce a FALSE output; Conditional Inputs depend on specific conditions outlined within an expression; and Variable Inputs can yield either TRUE or FALSE depending on their actual assigned values at the time of evaluation. Thus, TRUE inputs are the definitive factor in ensuring a TRUE outcome in Boolean logic.
