The correct response is:
Pseudocode is used in design to describe algorithms, while line comments succinctly describe the functionality and/or purpose of segments of code.
This accurately reflects the roles of both pseudocode and line comments in software development. Pseudocode serves as a high-level representation of algorithms, making it easier to understand the logic before actual coding begins. Line comments, on the other hand, are used to explain and clarify specific parts of the code itself, aiding in readability and maintenance.
