Which name is a valid namespace name?
A valid namespace name must follow DNS naming conventions, which require it to contain only lowercase alphanumeric characters or hyphens and cannot start or end with a hyphen. The options are: name$pace01, namespace-01, namespace_01, NameSpace 01. Option 'name$pace01' contains a dollar sign which is invalid. Option 'namespace_01' contains an underscore which is invalid. Option 'NameSpace 01' contains uppercase letters and a space, both of which are invalid. Therefore, the only valid option is 'namespace-01'.
