The correct answer is: A. makes logic decisions.
A logic gate is an electronic circuit that implements Boolean logic. Boolean logic is a form of logical expression that uses only two values: true and false, or 1 and 0. Logic gates are used to build digital circuits, which are the building blocks of computers and other electronic devices.
Option B is incorrect because logic gates do not allow electron flow only in one direction. In fact, most logic gates allow electron flow in both directions.
Option C is incorrect because logic gates do not work on binary algebra. Binary algebra is a system of arithmetic that uses only two digits: 0 and 1. Logic gates, on the other hand, use Boolean logic, which is a system of logic that uses only two values: true and false.
Option D is incorrect because logic gates do not alternate between 0 and 1 values. Logic gates can have a variety of output values, depending on the input values.
Option E is incorrect because logic gates are electronic circuits that implement Boolean logic.
