The statement is correct. Rapid inflation can indeed undermine money's ability to perform its functions. Here's why:

1. The future value of money cannot be predicted so money cannot act as a predictor of value: Inflation erodes the purchasing power of money over time. If inflation is rapid and unpredictable, it becomes difficult to know what a unit of money will be worth in the future, which undermines its function as a store of value.

2. People often revert to barter because money fails as a medium of exchange: If inflation is very high, people may lose faith in the currency as a medium of exchange. They might start to prefer barter or other forms of exchange, which can be more stable.

3. The value of money falls so money cannot serve as a measure of price: Inflation means that the price level is increasing, which means that the value of money is falling. If this happens rapidly, it can be difficult to use money as a unit of account or measure of price.

4. Money cannot hold sufficient value to act as a medium of value: If inflation is high, the real value of money – what it can buy in terms of goods and services – falls. This undermines its function as a store of value.

So, all the options are correct. Rapid inflation can undermine all the key functions of money.
