Step-by-step explanation:
Primary market is the initial market. Basically the starting point of any transaction which has a commercial substance.
In the chosen option the company is selling its shares to public initially as a new issue of stock, which creates the availability of stock in the market. Else in all another options the shares are already present in the market and interchanged by different people in the market.
Primary market is the one which introduces the product in the market, and not the one which provided for exchange within the market.
