Detailed explanation-1: -Historically, MAC addresses are 48 bits long. They have two halves: the first 24 bits form the Organizationally Unique Identifier (OUI) and the last 24 bits form a serial number (formally called an extension identifier).
Detailed explanation-2: -The correct option is 48 bits. CONCPET: The MAC address is a unique 12-digit hexadecimal numbers (48 bits in length) hardware address associated with a network adapter card, which is engraved on NIC at the time of manufacturing.
