Show answer & explanation
Correct answer: A
In digital logic diagrams, a small circle or "bubble" represents an inversion operation (NOT function). On a NAND gate, the bubble follows an AND structure, explicitly indicating that the combined AND gate's output is inverted (complemented). Therefore, option A is the correct choice.
