What type of market allows for immediate transactions on the spot?

The correct answer is the Spot Market. This market is characterized by the immediate execution of transactions, meaning that financial instruments, commodities, or securities are bought and sold for immediate delivery and payment. Transactions in the spot market are settled "on the spot," which distinguishes it from other markets where trades are executed at a future date or under different terms.

In contrast, the Futures Market involves agreements to buy or sell an asset at a future date at a predetermined price, which makes it suitable for hedging or speculating on future price movements rather than immediate transactions. The Money Market primarily deals with short-term borrowing and lending, often for maturities of one year or less, and while it may involve quick transactions, it does not fit the same definition of "immediate" as the spot market. The Long-term Market typically refers to the trading of securities with longer maturities, extending over several years, which again is not aligned with the concept of immediate transactions.

Overall, the Spot Market is specifically designed for immediate exchanges, making it the correct choice for this question.
