Explanation

grep performs case-sensitive search by default, meaning grep "Error" file.txt will not match lines containing "error" or "ERROR" - this is why D is correct. Option A is false because grep is one of the most fundamental Unix/Linux CLI tools, widely available across virtually all shells. Option B is fabricated - there is no scanconfig CLI command associated with grep; its behavior is controlled via flags like -i, -r, and -E. Option C is the classic trap: while grep -i enables case-insensitive search, that flag must be explicitly provided - the default behavior is case-sensitive.

Memory tip: Think of grep as a strict librarian who reads exactly what you write - you must say -i to get her to stop caring about capitalization.
