D) U.S. District Court
Failure to pay taxes, deliberately, can lead to criminal charges. If a man is accused of evading Federal income tax, the first court that would hear his case is the District Court.
The federal District Courts are the general trial courts, meaning that they are the first level of appeal (they have "original jurisdiction") regarding all civil and criminal cases that aren't within the jurisdiction of another court, for example, tax evasion.
