C Correct answer
Explanation

Optically Variable Ink (OVI) is a special security feature that changes color when viewed from different angles. In the Mahatma Gandhi series, the 500 and 1000 rupee notes had their numerals printed in this ink as an anti-counterfeiting measure. The 100 and 200 notes didn't use OVI for numerals, and the 10 rupee note was too low denomination to warrant this feature.
