C Correct answer
Explanation

The relationship is 'number: counting system based on that number of digits.' Decimal is base-10 (ten digits: 0-9), and binary is base-2 (two digits: 0-1). A septet means a group of seven, not a base-7 number system. Quartet means a group of four. Quince means fifteen in Spanish, not a number system.
