Explanation

Application modernization strategies fall into distinct categories. 'Invent in greenfield' means building a brand-new cloud-native application from scratch with no legacy constraints. 'Invent in brownfield' means creating a new cloud-native application to replace an existing one, but within an environment where legacy systems still exist - which is exactly what this organization is doing. Option A describes the process steps of a lift-and-modify migration, but 'Invent in brownfield' is the formal named strategy for replacing an existing on-premises app with a cloud-native version. The word 'brownfield' signals that an existing application/environment is being replaced or modernized, as opposed to starting with a clean slate (greenfield).
