Which extended ping IP header option allows you to specify one or more
hops over which the packets will travel without specifying the full path?
A.verbose
B.loose
C.strict
D.record 原答案给的是A， 可是verbose只是显示详细信息，并没有指定路径的功能啊，个人感觉选B，请大神们指教，谢谢！

根据思科文档：

[*] Verbose is automatically selected along with any other option.
[*]Record is a very useful option because it displays the address(es) of the hops (up to nine) the packet goes through.
[*]Loose allows you to influence the path by specifying the address(es) of the hop(s) you want the packet to go through.
[*]Strict is used to specify the hop(s) that you want the packet to go through, but no other hop(s) are allowed to be visited.
