Answer:
D. the legislative branch, requesting a new law in this area
Explanation:
The legislative branch of a government is saddled with the responsibility of making new laws and changing old laws. In the United States, this branch is composed of the House of Representatives and the Senate, making up the congress that writes or enact laws.
