Final answer:
The District Courts are the courts of original jurisdiction and typically hear federal legal cases for the first time. The correct option is A.
Step-by-step explanation:
Nearly all federal legal cases are heard for the first time by District Courts because it is the court of original jurisdiction.
The district courts serve as the entry point for most federal litigation and provide a forum where evidence is presented, witnesses testify, and cases are initially adjudicated. Above them in the hierarchy are the circuit courts, which handles appeals from district courts.
However, original jurisdiction at the district court level means they are the first to hear the cases brought before them, rather than reviewing decisions from lower courts.
Hence, Option A is correct.
