What is Amicus curiae brief?
What is Appellate jurisdiction?
What is Attorney general?

Explanation:

Amicus curiae brief is someone who is not part of a particular case but he/she is needed to give information or expertise words.

Appellate jurisdiction is the power infested on appellate court to amend, review or over rule a trial court or lower tribunal decision.

Attorney general is term given to the main legal advisor to the government on legal matter

the third answer is correct (c).

the laws that regulate the financing of political campaigns seek to guarantee the smoothness of funding so that there is no abuse of electoral economic power and to avoid the capture of future politicians by the donors.

this is because donor agents have their private interests that are not necessarily the same interests of the society that elected politicians must defend.

thus, interest groups should seek their interests within the legality of lobbying practices that are regulated.
