Identify the IUPAC name of the compound.

The given compound contains a four-membered carbon ring, which is a cyclobutane ring.

The principal functional group is the hydroxyl group ($-OH$), so the parent name is cyclobutanol. The carbon atom attached to the $-OH$ group is assigned position $1$.

There is a methyl group ($-CH_3$) attached to the adjacent carbon atom. To give the lowest possible locant to the substituent, this carbon is assigned position $2$.

Combining these parts, the IUPAC name of the compound is 2-Methylcyclobutanol.

Answer: 2-Methylcyclobutanol
