Final answer:
A murder case would most likely begin in a state court because state courts are responsible for criminal cases like robbery, ra_e, and murder, which are generally violations of state law. The correct answer is option a.
Step-by-step explanation:
The case that would most likely begin in a state court is a murder case. State courts handle the vast majority of criminal and civil cases, including crimes such as robbery, ra_e, and murder, which are typically violations of state law. Federal courts will hear cases involving federal questions, such as constitutional issues, federal laws, or treaties, or cases involving a federal party, like the U.S. government pressing charges. Therefore, options b, c, and d in the question outline situations that generally fall under federal jurisdiction, making 'a murder case' the most probable to start at the state level.
