JEE Main 2025 — 24 January, Evening Shift — Question 59

The output of the circuit is low (zero) for :

(A) $\mathrm{X}=0, \mathrm{Y}=0$

(B) $\mathrm{X}=0, \mathrm{Y}=1$

(D) $\mathrm{X}=1, \mathrm{Y}=1$

Choose the correct answer from the options given below :

The first gate is an OR gate:

X+Y

Its output is fed to a NOR (single-input) gate, i.e. NOT gate:

\text{Output}=\overline{X+Y}

Output is LOW when:

X+Y=1

This occurs for:

(0,1),\ (1,0),\ (1,1)
