The correct answer is:
For a cyclic process, $Q=-W$
According to first law of thermodynamics,
$$
\Delta U=Q+W
$$
For cyclic process, change in internal energy
$$
\begin{aligned}
&=0 \\
Q &=-W
\end{aligned}
$$
$$
\therefore \quad Q=-W
$$
$$
\Delta U=Q+W
$$
For cyclic process, change in internal energy
$$
\begin{aligned}
&=0 \\
Q &=-W
\end{aligned}
$$
$$
\therefore \quad Q=-W
$$
