A. B. C. D.D
The first three octets (bytes) of a MAC address represent the Organizationally Unique Identifier (OUI). The OUI is assigned by the Institute of Electrical and Electronics Engineers (IEEE) and identifies the vendor or manufacturer of the network interface card (NIC) or other networking hardware.
In the given MAC address 00: : :9f:eA., the first three octets are "00: : :9f". Therefore, the OUI in this MAC address is "00: : :9f".
Option B is not a valid option as it has extra colons in it which can't be used in MAC address. Option A only includes the last 3 bytes, and option C includes only the last two bytes, which are not the complete OUI.
Hence, the correct answer is option B, "00: : :9f".
