Final answer:
The creation of the source code is not necessarily the most expensive part of software development, as there are other factors that can contribute to the overall cost.
Step-by-step explanation:
The creation of the source code is not necessarily the most expensive part of the total software development effort. While writing the code can be time-consuming and require skilled programmers, other factors such as project management, testing, and debugging can also contribute to the overall cost.
For example, planning and coordination, ensuring the software meets the requirements, and fixing any issues that arise during testing can all require significant resources. Additionally, ongoing maintenance and updates to the software can also incur costs over time.
Therefore, while the creation of the source code is an important part of software development, it is not always the most expensive.
