A Certain Printer Requires That All of the Following Conditions

Multiple Choice

A certain printer requires that all of the following conditions be satisfied before it will send a HIGH to a microprocessor acknowledging that it is ready to print: 1. The printer's electronic circuits must be energized.
2. Paper must be loaded and ready to advance.
3. The printer must be "on line" with the microprocessor.
As each of the above conditions is satisfied, a HIGH is generated and applied to a 3- input logic gate. When all three conditions are met, the logic gate produces a HIGH output indicating readiness to print. The basic logic gate used in this circuit would be a(n) :

A) OR gate.
B) AND gate.
C) NOR gate.
D) NOT gate.
