A. $$\frac{{{\text{dQ}}}}{{\text{Q}}} = \frac{3}{2} \times \frac{{{\text{dH}}}}{{\text{H}}}$$
B. $$\frac{{{\text{dQ}}}}{{\text{Q}}} = 2 \times \frac{{{\text{dH}}}}{{\text{H}}}$$
C. $$\frac{{{\text{dQ}}}}{{\text{Q}}} = \frac{5}{2} \times \frac{{{\text{dH}}}}{{\text{H}}}$$
D. $$\frac{{{\text{dQ}}}}{{\text{Q}}} = 3 \times \frac{{{\text{dH}}}}{{\text{H}}}$$
