Aperson who strongly believes in the principle of federalism would favor a government where the federal government has the majority of government powers and responsibility power is as equally divided as possible between the state and central governments state and local governments share the bulk of government responsibility and power a president enforces all decisions made by a majority vote of the state governments

Lets summarize the options:  

government where the federal government has the majority of government powers and responsibility
no... that goes against the principle of federarism, this would be true for unitary states

 power is as equally divided as possible between the state and central governments state and local governments share the bulk of government responsibility and power

Now, i am not too sure if these are two options or onle one? in any case, this would be the correct in a federalism, the power and the responsibility is shared between the central and state governments. If these are two answers, then the better one is "power is as equally divided as possible between the state and central governments"

 a president enforces all decisions made by a majority vote of the state governments
-no... that's not the idea.
