A、 Each revision and the effective page should be logged in the logbook.
B、 Only the effective revisions pages need to be recorded in the manual.
C、 Each manual shall have a record of revisions or effective pages.
答案：C
解析：这道题考察的是手册的修订记录。正确答案是C，即每本手册都应该有修订记录或有效页面记录。这是非常重要的，因为当手册需要更新或修订时，我们需要知道哪些部分是最新的，哪些部分已经过时。这样可以确保我们使用的是最新的信息，避免出现错误。
举个例子来帮助理解，就好像你的手机操作手册一样。如果手机操作手册没有记录每次的更新或修订，你可能会被一些过时的信息误导，导致操作错误或者无法正常使用手机。所以，手册上的修订记录就像是手机操作系统的更新日志，帮助你了解手机的最新功能和操作方法。这样一来，你就能更好地使用手机，避免出现问题。
