Answer: (D)

Verified step by step guidance

1. Identify the functional groups present in the given molecule by examining the structure.
2. Look for a nitrile group, which is characterized by a carbon triple-bonded to a nitrogen (C≡N). In the structure, this is represented by the 'NC' group.
3. Identify the alcohol group, which is characterized by an -OH group attached to a carbon atom. In the structure, this is shown as the -OH group attached to the chiral center.
4. Look for an alkene group, which is characterized by a carbon-carbon double bond (C=C). In the structure, this is represented by the double bond in the carbon chain.
5. Identify the ether group, which is characterized by an oxygen atom connected to two alkyl or aryl groups (R-O-R'). In the structure, this is represented by the oxygen atom bonded to two carbon atoms.
