Final answer:
Minor criminal offences are typically held in Provincial courts, which deal with the majority of criminal cases involving less serious matters, while more serious cases are held in higher courts.
Step-by-step explanation:
Trials regarding minor criminal offences are generally held in lower-level courts that handle less serious matters. In the context of the Canadian justice system, this would be the Provincial court (Option B). The Provincial courts are responsible for the majority of criminal and regulatory offences and typically handle cases such as minor theft, traffic violations, and small claims. Superior courts, Court of Queen's Bench, and the likes handle more serious criminal offenses and have a wider jurisdiction over both criminal and civil matters. Appellate courts and state supreme courts generally handle appeals from the trial courts and do not conduct trials themselves.
