Suggested Answer: C 🗳️
Standard Ethernet frame MTU is 1500 bytes. This does not include the Ethernet header and Cyclic Redundancy Check (CRC) trailer, which is 18 bytes in length, to make the total Ethernet frame size of 1518. In this document, MTU size or packet size refers only to Ethernet payload. Ethernet frame size refers to the whole
Ethernet frame, including the header and the trailer. Baby giant frames refer to Ethernet frame size up to 1600 bytes, and jumbo frame refers to Ethernet frame size up to 9216 bytes.

No, the answer is correct. 1518 is the default frame size, including the header, payload and trailer. This size is not considering the 802.1q os ISL tags. A baby giant frame starts with 1600 bytes. The answer is C.
