请解释一下B选项 谢谢 还请问什么是Budget deficit谢谢

问题如下：

QuestionThe government implements a policy aimed at decreasing the budget deficit. This is most likely:

选项：

A.an expansionary fiscal policy.

B.a contractionary fiscal policy.

C.an instance of quantitative easing.

解释：

1. Incorrect. Reducing the budget deficit would slow the economy, not expand it.
2. Correct. A policy intended to decrease the budget deficit would involve increasing taxes and/or reducing spending. Either action is fiscal and would likely cause the economy to slow.
3. Incorrect. Quantitative easing is a monetary policy action and does not directly address the budget deficit, which is a fiscal concern.

• explain the implementation of fiscal policy and difficulties of implementation as well as whether a fiscal policy is expansionary or contractionary
