Final answer:
The segment limit relates to the segment length, providing bounds for addressable memory in a segment and facilitating memory protection.
Step-by-step explanation:
The segment limit in the context of memory management, specifically in segmented memory architecture, is primarily related to the segment length.
This means that the correct answer to the question is (c) segment length. The segment limit doesn't store the logical or physical addresses; instead, it defines the length of the segment, which essentially outlines the range of addresses that are valid for a given segment.
This limit is used for bounds checking to prevent a process from accessing memory segments that it's not supposed to, providing a measure of memory protection.
