| C. | NOT Gate | III. |  |
| D. | OR Gate | IV. |  |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → A-III, B-I, C-IV, D-II
Each gate symbol is built from a basic shape. The AND shape has a flat back and a round front, the OR shape has a curved back and a pointed front, and the NOT gate is a triangle. A small circle (bubble) at the output means the output is inverted.
(A) NAND Gate — this matches (III). It is the AND shape (flat back) with a bubble at the output.
(B) NOR Gate — this matches (I). It is the OR shape (curved back) with a bubble at the output.
(C) NOT Gate — this matches (IV). It is the triangle with one input and a bubble at the output.
(D) OR Gate — this matches (II). It is the OR shape with no bubble.
