C Correct answer
Explanation

ENIAC (Electronic Numerical Integrator and Computer) used decimal arithmetic, not binary. It was designed to perform calculations using decimal numbers (base-10) with 10 decimal digits per number, which was more intuitive for the scientists and engineers who used it. This decimal architecture was a design choice that differed from later binary computers.

AI explanation

ENIAC (Electronic Numerical Integrator and Computer), one of the earliest electronic general-purpose computers, is notable for using a decimal (base-10) numeral system rather than binary — it represented each digit using ten-position ring counters, unlike virtually all modern computers which are binary. So "Decimal" is correct; binary, octal, and hexadecimal are the numeral systems used by later computer architectures, not ENIAC.
