Call Markets vs Continuous Markets

Which of the following is most accurate with respect to the characteristics of call and continuous markets? Call markets \\ Continuous markets A. Used in larger markets \\ Price is often set by an auction process B. Used in smaller markets \\ Price may be set by dealer bid-ask quotes C. Trades occur at specific times \\ Smaller markets after the opening price is set D. Trades occur at any time market is open \\ Larger markets after the opening price is set


B. Call options are quite new and thus used in smaller market. For continuous market, dealer bid-ask quotes usually determines the price
