Final answer:
The crime that would most likely fall under federal jurisdiction is the sale of illegal fireworks by a convenience store owner.
Step-by-step explanation:
The crime that would most likely fall under federal, rather than state, jurisdiction is D. A convenience store owner is caught selling illegal fireworks out of her back room.
When a crime involves a violation of federal law, it typically falls under federal jurisdiction. In this case, the sale of illegal fireworks qualifies as a violation of federal law, as there are federal regulations and restrictions regarding the sale and distribution of fireworks. Therefore, the federal courts would be the appropriate jurisdiction for this crime.
