Answer:
1 is C, 2 is D
Step-by-step explanation:
For 1, the legislative branch makes laws, the executive branch executes the laws, and the judicial branch decides whether or not they're constitutional. None of the branches are in charge of any of the others.
For 2, D is the only option that is one branch limiting the power of the others. The president, (executive branch), limits the power of congress (legislative branch) by vetoing, or not allowing, laws.
