Question

This circuit acts as OR gate.
Reason Truth table for two input OR gate is

$A$	$B$	$Y$
0	0	0
0	1	1
1	0	1
1	1	1

• A. Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
• B. Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
• C. Assertion is correct but Reason is incorrect.
• D. Assertion is incorrect but Reason is correct.

Answer 1

Answer: (A)

Truth table for given circuit is

$A$	$B$	$X=\overline{A+B}$	$Y=\overline{X}$
0	0	1	0
0	1	0	1
1	0	0	1
1	1	0	1

Hence, the given circuit acts as OR gate.
