The correct answer is C. build a compelling business case for it. In the GInI Breakthrough Innovation Method, the Incubation and Selection step is focused on taking promising concepts and subjecting them to deeper evaluation, refinement, and validation. At this stage, teams do more than simply generate ideas. They gather additional information, perform analyses, and create enough structure around the concept to determine whether it is strategically sound, financially viable, and worthy of further investment.

This stage typically involves examining market attractiveness, customer value, feasibility, risk, alignment with business strategy, and potential returns. The purpose of this work is to convert an early concept into a more robust and defensible opportunity. A compelling business case becomes the outcome of that effort because leadership and stakeholders need clear evidence that the idea deserves continued support and resources.

The other options may relate to innovation communication or strategy development, but they do not reflect the core purpose of Incubation and Selection. This step is about disciplined evaluation and concept refinement so that the opportunity can be advanced on the basis of a strong and credible business case.
