Which of the following statements about a NAND gate is true?

A NAND gate is a type of digital logic gate that functions as the inverse of an AND gate. Understanding its operation requires knowing how it handles various combinations of input values.

The primary function of a NAND gate is that it outputs a low signal (0) only when all its inputs are high (1). Therefore, when all inputs are 1, the output indeed will be 0, which makes the first statement true.

When all inputs are 0, a NAND gate provides a high output (1). This means that the second statement is also true.

Finally, the third statement indicates that if one or more inputs are 1, the output will be 0. This is specifically true because the NAND gate only outputs 1 when all inputs are 0.

Since all the individual statements about the behavior of a NAND gate are accurate, it follows that the overall conclusion stating "All of the above" is correct, reaffirming that each condition described accurately reflects how a NAND gate operates.
