题目
Corporate bond secondary market trading most often occurs:
选项
A.on a book-entry basis.
B.on organized exchanges.
C.prior to settlement at T + 1.
答案
A
解析
： A is correct. The vast majority of corporate bonds are traded in over-the-counter (OTC) markets that use electronic trading platforms through which users submit buy and sell orders. Settlement of trades in the OTC markets occurs by means of a simultaneous exchange of bonds for cash on the books of the clearing system “on a paperless, computerized book-entry basis.” ： A是正确的。绝大多数公司债券在场外交易市场（OTC）进行交易，这些市场使用电子交易平台，用户通过这些平台提交买卖订单。场外交易市场的交易结算是在“无纸化、电脑化记账”的基础上，在结算系统的账簿上同时以债券换现金的方式进行的。
