In the context of a NAND gate, when all inputs are high (meaning they are at a logical 1), the output of the NAND gate is low (logical 0). This behavior is fundamental to the operation of NAND gates. A NAND gate operates on the principle that it produces a low output only when all its inputs are high. Thus, if you have two or more inputs and they are all at the high state, the NAND gate inverts the output, resulting in a low output.

Understanding this concept is crucial because NAND gates are universal gates, meaning they can be used to create any digital logic circuit. The configuration and behavior of NAND gates under various input conditions are essential for designing and analyzing these circuits.

In this scenario, recognizing that the NAND gate's distinct characteristic of producing a low output when all inputs are high directly leads to the correct answer. The unique inversion property of NAND gates makes them essential in digital circuit design.
