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.
Pseudocode helps in planning and outlining the structure of algorithms in a language-agnostic way, making it easier to understand the logic before actual coding. Line comments, on the other hand, provide explanations within the code, aiding in maintainability and readability by clarifying the purpose of specific code segments.
