To determine the size of the Instruction Register (IR) in a basic computer, we need to analyze the options given:

1. Understanding the Instruction Register (IR): The Instruction Register is a key component in a CPU that holds the current instruction being executed. The size of the IR typically corresponds to the architecture of the computer, indicating how many bits are used to represent the instructions.

2. Evaluation of Options:

   • 16 bit: This is a common size for many modern architectures.
   • 12 bit: Less common but may be used in some specialized or older systems.
   • 8 bit: Typically seen in very simple or older microcontrollers.
   • 6 bit: Rarely used in contemporary architectures.

3. Conclusion: The most prevalent sizes for Instruction Registers in modern computers are 16 bits and sometimes smaller configurations for specific architectures. Given the choices provided, 16 bit is likely the most suitable answer as the size.

Final Answer

The size of the IR in a basic computer is likely 16 bits.
