The heat pump is designed to move heat. This is only possible if certain relationships between the heats and temperatures at the hot and cold sides hold true. Indicate the statement that must apply for the heat pump to work. A. Q_{\rm h} < Q_{\rm c} and T_{\rm h} < T_{\rm c}.B. Q_{\rm h} > Q_{\rm c} and T_{\rm h} < T_{\rm c}.C. Q_{\rm h} < Q_{\rm c} and T_{\rm h} > T_{\rm c}.D. Q_{\rm h} > Q_{\rm c} and T_{\rm h} > T_{\rm c}.
