The reaction involves the addition of HBr to an alkene, following Markovnikov's rule. The hydrogen adds to the less substituted carbon, and the bromine adds to the more substituted carbon of the double bond. The major product is the most stable carbocation intermediate, leading to 2-bromo-2-methylbutane.

The correct structure is: CH3-CH-C(CH3)2-Br

Final Answer: The second option.
