Answer:
The correct answer is
A) An exchange of a long position in a fixed-rate bond for a short position in a floating-rate note.
Step-by-step explanation:
Swapping a fixed interest for a floating one can occur if the fixed interest tenure in comparison to a floating exchange rate becomes less expensive for the entity who took the loan.
Also executing a swap in interest rates (that is giving up the fixed tenure for the floating tenure) helps to ensure that liabilities are kept at minimum whilst assets are maximised.
It is important to note that the capital remains unmodified.
