Explanation

The command 'grep -i mandatory *' searches all files in the current directory (the wildcard * matches all files) for the string 'mandatory' in a case-insensitive manner (the -i flag). Using -i ensures that variations like 'Mandatory' or 'MANDATORY' are also matched, making it the most thorough and reliable search. 'grep mandatory *' (choice D) is similar but case-sensitive, potentially missing results. 'grep mandatory file' (choice C) only searches a single file literally named 'file'. 'grep -d mandatory *' uses -d which controls directory handling behavior, not case sensitivity, and is not the right flag for this task.
