Predict the major product in the following reaction :
`C_(6) H_(5)-CH_(2) CO_(2) CH_(3) overset((i) CH_(3) MgBr(Excess)) underset((ii) H^(oplus))rarr`.

Explanation

To predict the major product of the reaction between C6H5-CH2-CO2-CH3 and CH3MgBr followed by H+, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in the reaction are:
- C6H5-CH2-CO2-CH3 (which is an ester)
- CH3MgBr (a Grignard reagent)

### Step 2: Reaction of the Ester with Grignard Reagent
