When both a carboxylic acid group (-COOH) and a ketone group (C=O) are present in a chain, the final name will include "oxo" for the ketone group and "oic acid" for the carboxylic acid group.
This option does not accurately describe the nomenclature convention used when both a carboxylic acid group and a ketone group are present in a chain.
This option suggests that both option 1 ("oxo, oic acid") and option 2 ("One, Oic acid") are correct, but option 2 is not a standard naming convention for compounds containing both carboxylic acid and ketone groups.
This option implies that none of the provided options is correct.
The correct naming convention for a compound containing both a carboxylic acid group and a ketone group is A. Oxo, oic acid.
