Level 5

C.

The Software Capability Maturity Model (CMM) is a model that is used to evaluate the maturity of an organization's software development processes. The model is organized into five levels, which describe the maturity of an organization's processes, from an initial or ad-hoc state to a mature, disciplined process.

The five levels of the Software Capability Maturity Model (CMM) are:

1. Initial level: This is the starting point for any organization, where processes are ad hoc and unstructured.
2. Repeatable level: In this level, the organization has developed basic processes and is able to repeat them for similar projects.
3. Defined level: At this level, the organization has developed a set of standardized processes and procedures, which are followed for all projects.
4. Managed level: At this level, the organization is able to monitor and control the processes to ensure they are effective.
5. Optimizing level: In this final level, the organization continuously improves its processes through feedback and metrics.

Therefore, the answer to the question is option C, Fundamental level, as it is not a valid maturity level of the Software Capability Maturity Model (CMM).
