Which of these statements is correct?

Class 6Roman NumeralsNumbers
  • AIC is wrong; 99 must be written as XCIX
  • BIC is correct because 100 - 1 = 99
  • C99 cannot be written in Roman numerals
  • D99 should be written as XIC

Step-by-Step Solution

I can only be subtracted from V and X (giving IV, IX). So 99 = 90 + 9 = XC + IX = XCIX, not IC.
Answer: A) IC is wrong; 99 must be written as XCIX
