Solution

The correct option is C
Statement-1 is true but Statement-2 is false.

Hereassertion is correct but reasoning is incorrect. In presence of peroxide, addition of HBr on alkenes takes place via free radicals; here two free radicals are formed, $2^{\circ}$ free radical, being more stable, governs the product.
