Concept:The sequence involves multiple bromination reactions, adding bromine atoms to the organic molecule to form a polybrominated product.Explanation:Step 1: The starting material undergoes bromine addition across multiple unsaturated sites.Step 2: Subsequent steps introduce further bromine atoms via substitution or addition.In the final major product P, the structure contains a total of 5 bromine atoms attached to the carbon backbone.
Answer:The number of bromine atoms in the major product P is 5 (Option B).
