39Styrene oxide(epoxide group on double bond's place) and a carboxylic acid byproduct first, and then treated with H2SO4 for acidic hydrolysis of epoxide?
H2O is a relatively poor nucleophile(kyunki yeh acidic hydrolysis hai, I am assuming a general case of water from hydronium ion instead of HSO4- ion) in comparison to the leaving group O+H(protonated epoxide). So the rate at which it attacks an epoxide carbon is much slower than the rate at which O+H endeavours to cleave the C-O bond. This is an SN2 reaction with SN1 characteristics. The major product will be glycol with -OH attached to the carbon having Ph(as the transition state leading to the product can suck electrons from Ph), and the disconnected epoxide oxygen is now an OH at the beta carbon(isliye glycol).
