Which are the most active of the federal judiciary courts?

A - US District Courts

B - US Courts of Appeals

C - US Circuit Courts

D - Supreme Court

The correct answer is A - US District Courts

District courts are used for most general cases. The court of appeals comes after a district court while the Supreme court only handles select cases. This means that every next level has fewer cases since district courts solve most of the cases while a minority appeals to higher courts. They handle both civil and criminal cases.
