The correct option is Argo.

Argo is a Kubernetes native declarative GitOps family of tools that includes Argo CD for GitOps style continuous delivery. Argo CD was originally developed at Intuit which is a financial software company and the Argo project later joined the Cloud Native Computing Foundation and achieved graduated status, so it matches both parts of the question.

Spinnaker is a multi cloud continuous delivery platform that originated at Netflix and not a tool that was first created by a financial software firm, so it is incorrect.

Flux is indeed a declarative GitOps tool but it was created by Weaveworks rather than a financial software company, so it does not match the origin described in the question.

Kubernetes is a container orchestration system originally developed by Google and it is not a declarative GitOps delivery tool, so it is not the correct answer.
