C Correct answer
Explanation

In programming languages like COBOL, files can be opened in exactly four modes: INPUT, OUTPUT, I-O, and EXTEND. Similarly, Python defines four basic file open modes: read ('r'), write ('w'), append ('a'), and exclusive creation ('x'). Therefore, four is the standard correct answer.
