Gate symbol recognition (textual recovery): A 2-input NAND gate is represented by an AND-gate shape with a small inversion bubble at the output. Evaluate this description.

Introduction / Context:The original item referenced a figure. Applying the recovery policy, we restate a standard textual description: a NAND gate is commonly drawn as an AND gate with an inversion bubble on its output, indicating logical negation of the AND function.

Given Data / Assumptions:

• 2-input NAND gate.
• Standard schematic symbol conventions.

Concept / Approach:NAND implements NOT( A * B ). Symbolically, the AND gate shape denotes the product operation while the output bubble indicates inversion. This depiction is consistent across common drawing styles (IEEE/IEC) though graphic styles may vary.

Step-by-Step Solution:

Verification / Alternative check:Truth table of NAND equals the complement of AND; the bubble signifies this complement explicitly on the output node.

Why Other Options Are Wrong:

Common Pitfalls:Confusing input bubbles (which denote inversion at inputs) with the single output bubble for NAND.

Final Answer:Correct
