Answer:
B. a dealer buying newly-issued shares of stock from a corporation
Explanation:
Primary market transactions are IPOs or any other issuance of securities, e.g. bonds. A security is traded only once in a primary market, since after the security is issued for the first time, any other transection will be made on the secondary market. There is no physical difference between a primary or secondary market, e.g. the NYSE makes both primary and secondary transactions.
