Explanation

In Cisco IOx, the package.yaml application descriptor requires app.type: docker to identify a containerized Docker application - this is the valid, documented app type for Docker-based IOx applications. Option A (paas) is incorrect because paas refers to a Platform-as-a-Service app type used for non-containerized IOx apps that rely on the platform runtime. Option B (docker-vm) is a fabricated value with no meaning in IOx; there is no hybrid "Docker VM" type. Option D (docker-app) is similarly invalid - IOx does not hyphenate the type; the correct keyword is simply docker.

Memory tip: Think "keep it simple" - the app type mirrors exactly what it is. A Docker app uses docker, a PaaS app uses paas. No compound words, no hyphens.
