Question

In order to obtain an output, Y = 1, from the given combination of gates:

• A. A = 1, B = 0, C = 0
• B. A = 0, B = 1, C = 0
• C. A = 1, B = 0, C = 1
• D. A = 1, B = 1, C = 0

Hint:

An AND gate outputs 1 only when all its inputs are 1. If any input is 0, the output will be 0.

Answer 1

The Correct Option is C

Step 1: Analyzing the AND Gate.
An AND gate outputs 1 only when all of its inputs are 1. So for the AND gate to output 1, we need to analyze the input combinations:
- (A) A = 1, B = 0, C = 0: The output will be 0 because at least one input is 0.
- (B) A = 0, B = 1, C = 0: The output will be 0 because A = 0.
- (C) A = 1, B = 0, C = 1: The output will be 1, since A = 1, and C = 1.
- (D) A = 1, B = 1, C = 0: The output will be 0 because C = 0.

Step 2: Conclusion.
The correct combination of inputs for the AND gate to output 1 is (C) A = 1, B = 0, C = 1.
