Answer

The given compound can be numbered from left to right or vice versa. At the $2^{nd}$ position, there is a methyl group and is designated as $2-$Methyl.
The parent carbon chain contains $3$ carbon atoms resembling propane and at the positions $1$ and $3,$ there's the hydroxyl group designated as $1, 3-$diol.
So the $\ce{IUPAC}$ name of the given compound is $2-$Methylpropane$-1, 3-$diol.
