dbt Analytics Engineering Certification

dbt build runs selected models, tests, and snapshots in dependency order. The state:modified selector identifies new or changed resources against the manifest supplied through --state; --defer can resolve unselected upstream references to the comparison environment when they are not available in development. (docs.getdbt.com)

The selector must be written as state:modified, without a space after the colon. Without that correction, none of the choices is a valid invocation as written.
