Andre is predicting the products of chemical reactions. In one reaction, a hydrocarbon is the only reactant. What is the best prediction and explanation of this reaction?

A
Two new compounds form as the hydrocarbon undergoes a synthesis reaction.
B
Carbon dioxide and water form because the hydrocarbon undergoes a combustion reaction.
C
A polymer forms because the hydrocarbon joins with itself in a polymerization reaction.
D
Oxides form because the hydrocarbon combines with oxygen in an oxidation reaction.
