Which gates are represented by this figure 

(1) NAND gate

(2) AND gate

(3) NOT gate

(4) OR gate

If A and B are two inputs in AND gate, then AND gate has an output of 1 when the values of A and B are

(1) A = 0, B = 0

(2) A = 1, B = 1

(3) A = 1, B = 0 

(4) A = 0, B = 1

Symbol 

(1) NAND gate

(2) NOR gate

(3) NOT gate

(4) XNOR gate

To get an output 1 from the circuit shown in the figure, the input must be 

(1) A = 0, B = 1, C = 0

(2) A = 1, B = 0, C = 0

(3) A = 1, B = 0, C = 1

(4) A = 1, B = 1, C = 0

The output of the OR gate is 1 

(1) If both inputs are zero

(2) If either or both inputs are 1

(3) Only if both inputs are 1

(4) If either input is zero

The Boolean equation of NOR gate is 

(1) C = A + B

(2) $\mathrm{C}=\overline{\mathrm{A}+\mathrm{B}}$ 

(3) $C=A·B$ 

(4) $\mathrm{C}=\overline{\mathrm{A}.\mathrm{B}}$

This symbol represents
