The Nigerian Stock Exchange consists of the primary and secondary markets. The primary market is where new securities, such as stocks and bonds, are issued for the first time. This is also known as the initial public offering (IPO) market, where companies raise capital by selling their shares to the public.
On the other hand, the secondary market is where previously issued securities are bought and sold among investors. This is where individuals and institutions trade these securities after they have been issued in the primary market. The secondary market is also known as the stock market or the equity market.
Therefore, the correct answer is the **secondary and primary market**.
