greet "Bob"

But running it gives: main.sh: line 2: greet: command not found

CThe greet function is called before sourcing lib.sh

Step 2: Analyze error message
"command not found" means the function is missing, not a syntax or permission error.
Final Answer:
lib.sh does not define the greet function -> Option A
Quick Check:
Missing function definition = lib.sh does not define the greet function [OK]
