Explanation:
Answer: Option (d) is the correct answer.
Explanation:
An oxidizing agent is a specie which accepts electrons and gets reduced in a chemical reaction.
In the given reaction,
Oxidation state of Al changes from 0 to +3, therefore, it is reducing agent. Whereas oxidation state of Br is changing from -2 to -3 this means Br is gaining electrons, therefore, it is an oxidizing agent.
Thus, we can conclude that the statement is the oxidizing agent because its oxidation number decreases.
It takes more energy to breakdown the bonds
