Two compounds, A and B, have the same molecular formula (C6H12). Interestingly, both A and B react with a peroxy acid (RCO3H) to form epoxides. What can we infer about compounds A and B based on this information?
A. They must have identical structures.
B. They are definitely different isomers.
C. They likely have similar functional groups.
D. More information is needed to determine their structures.
