To name the compound, we need to identify the longest carbon chain and the functional groups present, then apply IUPAC nomenclature rules.

Identify the functional groups and the longest carbon chain.
The compound has a carboxylic acid group ( $\text{COOH}$ ) at one end and a hydroxyl group ( $\text{OH}$ ) at the other end. The longest continuous carbon chain containing the carboxylic acid group has three carbon atoms.
Number the carbon chain.
The carbon atom of the carboxylic acid group is always designated as carbon 1.
So, the chain is numbered as follows:
$\text{C}_1$ (from $\text{COOH}$ ) - $\text{C}_2$ - $\text{C}_3$ (with $\text{OH}$ )
Determine the parent name based on the principal functional group.
The principal functional group is the carboxylic acid. A three-carbon carboxylic acid is called propanoic acid.
Identify and name any substituents.
There is a hydroxyl ( $\text{OH}$ ) group on carbon 3. When $\text{OH}$ is a substituent, it is named "hydroxy".
Assemble the full name.
Combine the substituent name and position with the parent name.

The name of the compound is $\text{3-hydroxypropanoic acid}$ .
