Answer:
I. Federal Trade Commission.
III. Department of Justice.
Step-by-step explanation:
The Hart-Scott-Rodino Act of 1976 is actually a complement of prior antitrust laws that already existed but were incomplete or outdated. Its main focus is set on a pre-merger notification report that must be given by the parties involved to the Federal Trade Commission (FTC) and the Department of Justice (DOJ). The HSR Act only applies to mergers or acquisitions that are relatively large, e.g. the transaction must involve at least $90 million.
