Refer to the exhibit. When applying this hierarchical policy map on the on the tunnel1 interface, you measure high jitter for traffic going through class 1234. What is the most likely cause of this jitter?（）

• A、The configuration of a hierarchical policy map on a tunnel interface is not supported.
• B、Class 5555 and class 5554 are both taking up 100% of the bandwidth，leaving nothing for class 1234.
• C、The burst size for the traffic shaping is wrongly configured to 15000；this would require an interface capable of sending at 150Mb/s.
• D、The burst size for the traffic shaping has been wrongly configured；it should be set as low as possible.
• E、The burst size for the traffic shaping has been wrongly configured；it should be set as high as possible.
