Which of the following is not a specialized sub market of the money market ?

The money market deals in short-term funds, and its specialised sub-markets include the call money market, the collateral loan market, the acceptance market and the bill or discount market. The bond market deals in long-term debt and so belongs to the capital market. Collateral loans, discounting of bills and acceptances are all short-term instruments, which is why they are money-market sub-markets.
