When troubleshooting a network， the output of the command show interfaces indicates a large number of runts. What is a runt？（）

• A、the number of packets that are discarded because they exceed the maximum packet size of the medium
• B、errors created when the CRC generated by the originating LAN station or far-end device does not match the checksum calculated from the data received.
• C、the number of packets that are discarded because they are smaller than the minimum packet size of the medium
• D、the number of received packets that were ignored by the interface because the interface hardware ran low on internal buffers
• E、the number of times that the interface requested another interface within the router to slow down
