Examiners report
Although this question was one that was common to HL, the SL candidates found it to be much more difficult. Perhaps this has to do with the fact that more HL candidates also do Chemistry than SL candidates. It was a very good discriminator with almost all of those getting it incorrect choosing B, showing confusion between the structures of glucose and ribose.
