D . MSS

View Answer

Answer: D

Explanation:

Option D (MSS – Maximum Segment Size) is correct because it refers to the maximum amount of data that can be received in a single TCP segment. Adjusting MSS can help minimize the risk of fragmentation on a GRE/IP tunnel because it ensures that TCP segments are small enough to fit within the GRE/IP packets without needing fragmentation.
