Answer:
The correct option reads "the act of simultaneously buying and selling the same or equivalent assets or commodities for the purpose of making certain guaranteed profits."
Step-by-step explanation:
An arbitrage typically is about taking advantage of price differentials which results in a guaranteed level of gains.
For instance,buying US dollars in one city and sending it via bank transfer to a buyer in another city because the rate of exchange in the other city is higher ,there making an instant guaranteed profit resulting from the price differentials.
However, one of the reason for such is that information in one market might be stale while the other market is up-to-date with market information.
