(D) The COCOMO model is not a software process model
The Linear Sequential Model, also known as the Waterfall Model, the Prototyping Model, and the Spiral Model are all software process models. They provide a structured sequence of stages in software development.
On the other hand, the COCOMO (Constructive Cost Model) is a predictive model that estimates the cost, effort, and schedule for a software project. It’s not a process model, but rather a method of predicting the various parameters associated with software development
