The correct response is: State and federal governments have the same three branches of government, but they differ in size and scope.
Both state and federal governments are structured with an executive branch, a legislative branch, and a judicial branch. However, the size, scope, and specific powers of these branches can vary between the two levels of government. State governments have their own constitutions, laws, and regulations, which give them authority over various matters, while the federal government has broader powers that are enumerated in the U.S. Constitution.
