The IUPAC name of $CH X_{2} = CH - CH (OH) - C \equiv C - CH X_{3}$ is:

Ahex-4-yn-1-en-3-ol
Bhex-5-en-2-yn-4-ol
C3-hydroxyhex-1-en-4-yne
Dhex-1-en-4-yn-3-ol

Answer: D

The OH gets the lowest locant: from the vinyl end it is C-3, from the other end C-4, so number from the vinyl end. The ene is at 1 and the yne at 4, cited as -en-yn- before -ol. The name is hex-1-en-4-yn-3-ol.
