Answer:
The blank in the question is asking for an item that fits appropriately in the Legislative branch of government's check. The Legislative branch is responsible for making laws. Now, let's look at the answer choices:
A. Proposes treaties
B. Declares executive orders legal
C. Approves constitutional amendments
D. Overrides vetoes
Out of these options, the item that fits appropriately in the blank is D. Overrides vetoes. This is because one of the checks and balances of the Legislative branch is the power to override a presidential veto. If the president vetoes a bill (rejects it), the Legislative branch can vote again and if two-thirds of both the House of Representatives and the Senate vote in favor of the bill, it becomes a law despite the president's veto.
Therefore, the correct answer is D. Overrides vetoes.
