Which of the following relations is correct according to Boolean algebra?

The output $(Y)$ of the logic circuit given below is $0$ only when:

In the logic circuit diagram,when all the four inputs $A, B, C, D$ are $1$,the outputs $Y_1, Y_2, Y_3$ are respectively $(1, 1, 0)$. When all the inputs $A, B, C, D$ are changed to $0$,the outputs $Y_1, Y_2, Y_3$ respectively change to

The given symbol represents:

The truth table given below is for which gate?
$A: 0, 0, 1, 1$
$B: 0, 1, 0, 1$
$C: 1, 1, 1, 0$

Write the truth table of $NAND$ gate.
