[单选题]
07.39: A mass of materia x6wi3c6 wqymm/d j4 ;ccl4(kvl exists in its solu/ ev( r+;8v ;+0rdcoudptj tmid form at its melting temperature $10^{\circ}C$. The following processes then occur to the material:
Process 1: An amount of thermal energy Q is added to the material and $\frac{3}{4}$ of the material melts.
Process 2: An identical additional amount of thermal energy Q is added to the material and the
material is now a liquid at $500^{\circ}C$.
What is the ratio of the latent heat of fusion to the specific heat of the liquid for this material?

A. $80^{\circ}C$
B. $60^{\circ}C$
C. $40^{\circ}C$
D. $20^{\circ}C$
