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

Apent-1-en-4-ol
Bpent-4-en-2-ol
Cpent-3-en-2-ol
D4-hydroxypent-1-ene

Answer: B

Number so the OH gets the lowest locant: from the CH3 end the carbinol carbon is C-2, from the other end it would be C-4. With this numbering the double bond is C-4=C-5. The name is pent-4-en-2-ol.
