What is the major product obtained from the following reaction (assume enantiomer is also formed)?

Question

The reaction is a standard nucleophilic substitution (SN1) reaction with tert-butyl bromide and water as the nucleophile. The first step is the formation of a carbocation intermediate, which can undergo either hydride shift or methyl shift to produce a more stable carbocation. In this case, a methyl shift is more favorable, as it leads to a tertiary carbocation. The nucleophile then attacks the carbocation at the site with partial positive charge, leading to alcohol formation. Since the starting material is optically inactive, the product will be a racemic mixture of enantiomers. The major product in this reaction will be the more stable tertiary alcohol II.
