A and B is the input of AND gate then we will get output A.B and A.B is the input of NOT gate we will get output bar of A.B,

Here combination of NOT, AND gate is called NAND gate.

IF A AND B ARE INPUT OF THE AND GATE THEN THE OUTPUT IS AB
NAND GATE IS THE COMBINATION OF NOT and AND GATE then the output is the negation of AND gate
so AB-- = NAND

NAND gate is derived from AND gate. The starting N describes the bar. In the and gate output is AB. Therefore in NAND gate out put must be AB whole bar.

A and B for AND gate here given AB bar so inverted gate so AND inverted gate NAND so option A.

It's NAND gate.
