The choice that is not a lifecycle model of software development is one that does not align with established methodologies or frameworks used in the software development process.

Incremental development is a well-known lifecycle model where the product is designed, implemented, and tested incrementally (a little more is added each time) until the product is finished. Agile, based on iterative development, emphasizes flexibility and customer involvement, allowing for changes to be made throughout the development process.

The term "Agnostic" in the context of software development does not refer to a specific lifecycle model but rather suggests an absence of commitment to a specific technology or methodology. It implies a more general approach rather than a defined step-by-step framework for development.

On the other hand, "Cluster" does not represent any recognized model in the software development lifecycle. Models typically include various methodologies with structured processes for development and management that are validated and widely recognized within the industry.

Thus, the correct answer identifies the option that does not fit within the established categories of software development lifecycles.
