Correct answer
COne acetal and one hemiacetal

Step-by-step explanation

Cyclic hemiacetal are formed when an alcohol oxygen atom adds to the carbonyl carbon of an aldehyde or a ketone. Molecules (aldehyde or ketone), which contain both an alcohol and a carbonyl group, can instead undergo an intramolecular reaction to form a cyclic hemiacetal/ hemiketal.
