D Correct answer
Explanation

The 'bc' command (Basic Calculator) is the standard Unix/Linux command-line calculator utility that supports arbitrary precision arithmetic. The 'cal' command displays calendars, not a calculator, and 'basic' and 'calculator' are not standard calculator commands in Unix/Linux systems.
