Coins and prints currency
The responsibilities of the legislative branch are defined by Article 1 of the Constitution of the United States. So let's look at the options and see if they're OK.
Coins and prints currency
* This is specified in Article 1, Section 8, line 5. So this is a correct choice.
Approves and carries out laws
* The executive branch enforces or carries out the law. So this is a bad choice.
Spends money authorized by Congress
* Congress is the legislative branch. And money is spent by the executive branch. So this too is a bad choice.
Determines jurisdiction for court cases
* This would be the providence of the Judicial branch, not the legislative. So this is a bad choice.
