Solution

The correct option is C Pent-1-ene-3-ol
The IUPAC name for $C H_{3} C H_{2} C H (O H) C H = C H_{2}$ is $P e n t - 1 - e n e - 3 - o l .$

It contains 1 double bond at 1st carbon atom and 1 functional group $- O H$ on 3rd carbon atom.

$5 C H_{2} - 4 C H_{2} - O H 3 | C H - 2 C H = 1 C H_{2}$
$P e n t - 1 - e n e - 3 - o l .$

So, the correct option is $C$
