Why each option
This question asks to identify a valid command-line option that can be used with the `ping` utility.
`packet loss` is an output metric of the ping command, not an input option.
The `packet size` option, typically specified with a parameter like `size` or `-s` in various `ping` implementations, allows the user to define the data payload size of the ICMP echo request packets. This is a common and valid feature for network troubleshooting, allowing testing of various MTU scenarios.
`CRC` (Cyclic Redundancy Check) is a data integrity mechanism at the data link layer and is not a configurable option for the `ping` command itself.
`TCP port` is relevant for TCP-based connectivity tests, but `ping` uses ICMP, not TCP, so it does not have a TCP port option.
