Attempted by 169 students.
Show answer & explanation
Correct answer: D
The correct answer is Option D, the Exclusive-OR (XOR) gate.
The graphic symbol shown features a distinctive curved input line combined with a double-curved back, which is the standard IEEE/ANSI representation for an XOR gate.
This specific shape differentiates it from other gates: an OR gate has a single curved back, while a NAND or NOR gate includes a small circle (bubble) at the output to indicate inversion.
The XOR gate produces a high output only when its inputs are different, meaning one is true and the other is false. Recognizing this unique double-curve symbol allows you to immediately identify it as an XOR gate, ruling out the OR, NAND, and NOR options which have different structural features. Therefore, based on standard logic gate symbols, the correct identification is Option D.
