What trend, if any, is evident in Mel's data?
 Select one:
 O a. The lower the density of the metal, the higher the melting
 point. The hypothesis is not supported.
 O b. There is no correlation between density and melting point.
 Mel's hypothesis is not supported.
 O c. Mel's hypothesis is supported; the denser the metal, the higher
 the melting point.
 O d. Initially, there seems to be support for Mel's hypothesis, but
 the gold data is not consistent with the predicted trend.
