The correct answer is: B. Logic gates
Logic gates are the building blocks of all the circuits in a computer. They are used to perform basic operations such as AND, OR, and NOT. Logic gates can be combined to create more complex circuits, such as adders, subtractors, and
multipliers.A circuit switch is
a device that connects two or more circuits together. It is used to control the flow of data in a computer.Logical operators are used to compare two values and return a Boolean value (true or false). They are not used to build circuits.
Instructions are the commands that a computer executes. They are not used to build circuits.
None of the above is the correct answer.
