Best answer
The correct option is (b) NAND gate

Explanation: The NAND gate consists of two inputs and if both of them are high the output is low. A luggage security alarm circuit is a system which is based on the NAND gate. It is used to generate an alarm when any authorized person tries to steal the luggage.
