(b) From real time variation of input signals, we can from truth table for $A$ and $B\ $and conclude output from NAND gate.
[table] $\mathbf{Inputs}$ | $\mathbf{Output}$ ; $\mathbf{A}$ | $\mathbf{B}$ | $\mathbf{Y}$ ; $0$ $1$ $0$ $1$ $0$ | $0$ $0$ $0$ $1$ $0$ | $1$ $1$ $1$ $0$ $1$ [/table]
From output, we can show real time variation of output signal as below.
