<u>Answer</u>:
Seminoles were a threat to Georgia because (C): They sheltered runaway slaves and would not return them.
<u>Explanation</u>:
The term Seminole was the name of a tribe of Native America which was formed by the people who had settled in Florida in the 18th century, especially in Georgia and Alabama. The Seminoles formed their own identity and traditions such as the use of ritual beverages and tobacco and therefore became independent from other groups.
During the 17th century, many black slaves started escaping from Georgia to Spanish Florida looking for liberty, which was given to them in exchange of protecting the town. As the Seminoles started to welcome all escaped African slaves, and even accepted the intermarriage with the former ones, their group started expanding until they eventually come to be known widely as the Gullah people.
Several countries including Georgia, showed their irritation of the situation and caused the US army to invade the Seminoles territory in order to recapture the escaped slaves.
