The manual of an electric shower informs that its three heating levels (warm, hot, and superhot) present the following variations in water temperature as a function of its flow rate:

\begin{center}
\begin{tabular}{ | c | c | c | c | }
\hline
\multirow{2}{*}{Flow rate $\left( \frac{\mathrm{L}}{\mathrm{min}} \right)$} & \multicolumn{3}{|c|}{$\Delta \mathrm{T} \left( {}^{\circ} \mathrm{C} \right)$} \\
\cline{2-4}
 & Warm & Hot & Superhot \\
\hline
3 & 10 & 20 & 30 \\
\hline
6 & 5 & 10 & 15 \\
\hline
\end{tabular}
\end{center}

A circuit breaker is used to protect this shower circuit against electrical overloads at any heating level. By standard, the circuit breaker is specified by the nominal current equal to the multiple of 5 A immediately higher than the maximum current of the circuit. Consider that the shower should be connected to 220 V and that all energy is dissipated through the shower's resistance and converted into thermal energy transferred to the water, which has a specific heat of $4.2 \frac{\mathrm{~J}}{\mathrm{~g~}^{\circ}\mathrm{C}}$ and density of $1000 \frac{\mathrm{~g}}{\mathrm{~L}}$.\\
The circuit breaker suitable for protecting this shower is specified by:\\
(A) 60 A\\
(B) 30 A\\
(C) 20 A\\
(D) 10 A\\
(E) 5 A
