Step-by-step solution

Alkene gives the hydroboration oxidation reaction. It formed the alkene to alcohol. After that the alcohol is oxidised into the aldehyde by the PCC . After that Grignard reagent followed by the hydrolysis gives the nucleophilic addition reaction. It converts the aldehyde into the secondary alcohol. Reaction :- Hence, the major product of this reaction is .
