Answer:
Representatives are authorized to deposit and withdraw on our behalf because they were chosen by us.
Explanation:
Representatives are elected by the majority of the population through voting. This means that they are chosen and authorized to represent the people and to act on behalf of that population. In this case, the representatives, literally, must represent us in the legal and political processes that are established in our region, and can even deposit or withdraw in our name, if that represents our desire.
