The action to be taken in a program is called a ________________.

• A. Step
• B. Command
• C. Basic
• D. Assemble

Answer: (B)

In programming, an instruction that tells the computer exactly what to do next is called a command. Commands specify concrete operations the program should perform, such as moving a motor, reading a sensor, calculating a value, or displaying output. Programs are executed as a sequence of commands, each carried out in order to achieve the overall task. A step is related—it's a single part of an algorithm—but the typical term for an executable instruction in a program is a command. Basic and assemble don’t describe the action to be taken by the program: basic is a level of language, and assemble refers to putting pieces together or assembling code, not the action itself. Therefore, the action to be taken in a program is called a command.
