Given the use of upper case, I personally would initially assume Roman numerals*, so the answer would be C (100 in present-day decimal notation)

*Note that the abbreviation XL (for XXXX) appeared quite late in the Roman period, and never found universal favour

and for binary would be
11010X
What nonsense did you hear today in India that made you laugh?
What is the sum of X+XX+XXX+XXXX?
1234X
However, X +X^2 +X^3 + X^4 is a valid algebraic answer,
