D. Ph−CH2−CH2−CH2−OHPh - {CH}_{2} - {CH}_{2} - {CH}_{2} - OH

Step-by-step solution

The Hydroboration Oxidation reaction is an organic chemical reaction which is employed for the conversion of alkenes into alcohols that are neutral.

The hydroboration oxidation reaction mechanism can be considered as an anti-markownikov's reaction where a hydroxyl group attaches itself to the carbon which is less substituted. 

The final product A, formed in the following reaction sequence is:

Hence, the answer is option D.
