C Correct answer
Explanation

In Roman numerals, M represents 1000 and C represents 100. When a smaller numeral appears before a larger one, it's subtracted. Therefore, CM means 1000 minus 100, which equals 900. This subtractive principle is standard in Roman notation - IV is 4 (5-1), IX is 9 (10-1), and CM is 900 (1000-100).
