Final answer:
None of the options provided (I, V, VII, XII) represent a number over 90. In Roman numerals, XC represents 90. The numbers listed might have an error as none correspond to over 90.
Step-by-step explanation:
The student has asked a question concerning Roman numerals. Specifically, the question seeks to identify which of the provided options represents a number over 90. The options given are Roman numerals, and they each represent the following Arabic numerals: I (1), V (5), VII (7), and XII (12). None of these options are over 90.
However, looking at the context provided, where Roman numerals are listed, we can see that the intent might be to identify which numerals represent numbers over 90 within a list. Numbers like XC (90), XCI (91), XCII (92), etc. would qualify.
Though none of the options presented in the question are over 90, perhaps the question had a typographical error and meant to include an option like XCX or XC, which would be correct answers.
The correct Roman numeral for 90 is XC, and for the number 91 it is XCI. If the student is indeed asking which provided option is over 90, they might have encountered an error as none of the options listed (I, V, VII, XII) correspond to a number greater than 90.
