The figure shows a combination of two NOT gates and a NOR gate.
The combination is equivalent to $\mathrm{a}$

• A

  NAND gate
• B

  NOR gate
• Correct answer
  C

  AND gate
• D

  OR gate

Solution

Truth table is as shown :
Thus the combination of two NOT gates and one NOR gate is equivalent to a AND gate.

Hence, the correct answer is option: 'C'.
