Question Analysis

The question is asking about the lowest level of programming language that a computer can understand based on its hardware design. This entails understanding the different types of programming languages available.

Options Explanation

1. Machine Language: This is the most fundamental language that a computer understands, consisting of binary code (0s and 1s).
2. Assembly Language: This is a higher-level representation of machine language, using mnemonics and symbols that represent machine-level instructions but still closely aligned with the hardware.
3. High-Level Language: These languages (like Python, Java, etc.) are more abstract and require a translator (compiler or interpreter) to convert them to machine language.
4. Medium Language: This term is not widely recognized in the context of programming language classifications.

Conclusion

Given that computers operate directly on the binary instructions provided by machine language, the correct answer to the question is:
