The exchange of a fixed interest rate cash flow for a floating interest rate cash flow with both interest rates in the same currency is an example of:

The scenario describes the fundamental structure of a "plain vanilla" interest rate swap. This is the most common type of interest rate swap, where two counterparties agree to exchange cash flows on a specified notional principal amount for a predetermined period. One party makes payments based on a fixed interest rate, while the other makes payments based on a floating interest rate, with both payment streams denominated in the same currency. This arrangement allows entities to manage their exposure to interest rate fluctuations.

B. an interest rate option: This is incorrect because an option provides the holder the right, but not the obligation, to a transaction. The question describes a mandatory exchange of cash flows.

C. a basis-rate swap: This is incorrect as a basis swap involves exchanging two different floating interest rate cash flows, not a fixed rate for a floating rate.

D. an interest rate cap: This is a type of option that protects the buyer from rising interest rates by paying out when a reference rate exceeds a specified "cap" rate. It is not an exchange.
