The command that can be used to determine whether serial interface 0/2/0 has been configured using HDLC encapsulation is the
show interfaces command.
Out of the options given, the correct command is

Here's a breakdown of the other options:
router#show platform: This command displays information about the hardware platform, such as the processor type and memory usage. It does not provide information about interface configuration or encapsulation.
router#show ip interface s0/2/0: This command displays IP-specific information for the specified interface, such as the IP address and subnet mask. It does not provide information about the encapsulation type.
router#show ip interface brief: This command displays a summary of all interfaces on the router, including their status and IP addresses. It does not provide information about the encapsulation type.
Therefore, the correct command to determine the encapsulation type used on serial interface 0/2/0 is
router#show interfaces Serial 0/2/0.
