The best resource for comparing and contrasting information on cancer diseases would be option C --The science of malignant tumors. Option A is about how to beat a specific type of cancer but it does not compare or contrast information on different types of cancer.

Option D is a medical dictionary which probably contains information about different kinds of cancer, but to use it, the reader should know what word to look up. Option C is the only one addressing malignant tumors, and therefore, it is to be expected to provide information to compare and contrast different types of cancer.
