A. money no longer functions as a good store of value and people may resort to barter transactions on a much larger scale.

Explanation:

Hyper Inflation can be defined as inflation i.e price rise occuring at highly accelerating pace.

Such exponentially rising prices reduce the value (purchasing power) of money.
