X and Z are (A) positional isomers.

Explanation:

1. Grignard reaction

The Grignard reaction of an alkyl halide with an aldehyde gives a secondary alcohol.

1-phenylethanol

2. Dehydration

The reaction of an alcohol with hot concentrated sulfuric acid gives an alkene.

ethenylbenzene

3. Hydroboration/oxidation

The hydroboration/oxidation reaction gives the anti-Markovnikov addition of water to an alkene.

2-phenylethanol

Thus, 1-phenylethanol (X) and 2-phenylethanol (Z) are positional isomers.
