Which level(s) of the federal judicial system has/have both original and appellate jurisdiction?
Level 3
Supreme Court
Level 2
U. S. Courts of Appeal
Level 1
U. S. District Courts
A. Level 1
B. Levels 1 and 2
C. Level 3
D. Levels 2 and 3

I'm pretty sure it's not the Supreme Court, since it's the final answer to legal questions, like there is no appealing a Supreme Court decision. So I think it would be both of the other two, the District and Courts of Appeal. Hope this helps.
