A potential criticism of a high fiscal deficit:

Increased investment
Inflation
Stable currency
Economic growth

The correct answer is: B) Inflation.

A fiscal deficit is the amount by which a government’s spending exceeds its revenue in a given year. When a government runs a fiscal deficit, it must borrow money to finance its spending. This borrowing can lead to inflation, as the government adds more money into the economy. Inflation can make it more difficult for businesses to plan and invest, and it can also erode the value of savings.

Increased investment is not necessarily a criticism of a high fiscal deficit. In fact, some economists argue that government spending can be a good way to stimulate investment. However, if the government borrows too much money to finance its spending, it can lead to inflation, which can discourage investment.

A stable currency is not necessarily a criticism of a high fiscal deficit. In fact, some economists argue that government spending can help to stabilize the currency. However, if the government borrows too much money to finance its spending, it can lead to inflation, which can destabilize the currency.

Economic growth is not necessarily a criticism of a high fiscal deficit. In fact, some economists argue that government spending can help to stimulate economic growth. However, if the government borrows too much money to finance its spending, it can lead to inflation, which can slow down economic growth.

In conclusion, the potential criticism of a high fiscal deficit is inflation.
