What is IUPAC name of following compound?

Identifying the IUPAC name requires analyzing the structure: a cyclobutane ring with substituents including a methoxy group and two methyl groups.

Numbering begins at the carbon bearing the methoxy group to maintain the lowest possible locants. The adjacent carbon, with two methyl groups, is assigned position 2.

The correct name is $\text{1-methoxy-2,2-dimethylcyclobutane}$, matching option C. Option A and B incorrectly identify the parent as butane rather than cyclobutane, and option D uses non-optimal numbering for the methoxy group.
