Which command starts a build for a given build config with an environment variable KEY=VALUE using the exact syntax without quotes?

Which command starts a build for a given build config with an environment variable KEY=VALUE using the exact syntax without quotes?

• A. oc start-build web-app --env=BUILD_LOGLEVEL=4
• B. oc start-build web-app --env=BUILD_LOGLEVEL="4"
• C. oc set env bc/web-app BUILD_LOGLEVEL=4
• D. oc logs -f build web-app

Answer: (A)

To start a build for a BuildConfig while injecting an environment variable for that run, you pass environment overrides directly to the start-build command using --env KEY=VALUE. This starts a new build for the specified BuildConfig and applies the variable only to that build instance, without changing the BuildConfig itself. The exact form uses no quotes: oc start-build web-app --env=BUILD_LOGLEVEL=4. Using quotes isn’t necessary and isn’t required by the prompt’s constraint, though in practice shell quoting often gets stripped. The other options either update the BuildConfig itself (oc set env bc/web-app BUILD_LOGLEVEL=4) or are not about starting a build (oc logs -f build web-app).
