This reaction is an electrophilic addition reaction with an alkene. This is one of many alkene addition reactions that can add an -OH group onto your starting material. The key aspect of an hydroboration-oxidation reaction is the anti-Markovinikov addition to the double bond. The -OH group should be on the least substituted of the two carbons that originate from the double bond. In light of this information, the answer is 2-cyclohexanol.

5-hydroxyvaleric acid (5-hydroxypentanoic acid) is a five-carbon carboxylic acid alcohol and will produce the required lactone. This reaction is typically acid-catalyzed. Pentanedioic acid (glutaric acid) is a linear dicarboxylic acid, 4-hydroxybutyric acid only has four carbons and will not produce the desired product without being modified.

The substrates must be modified in order to attain the desired product. In order to get the desired product, she needs to change one of the alcohol groups into a good leaving group. One way to do this is to react the methanol with to create a primary tosylate. Because of its advanced resonance, tosylate is an extraordinary leaving group, and so the ethanol is free to attack the modified substrate to form an ether.
