IP option sizes are represented in how many bytes?

• A. 0
• B. 2
• C. 1
• D. 8

Answer: (C)

IP option sizes are represented in one byte. Each IPv4 option has a 1-byte kind, a 1-byte length, and then the data. The length field specifies the total length of that option in bytes, so the size is encoded using a single byte (up to 255 bytes).
