The urban areas of Canberra are organised into a hierarchy of group centres

Step 1: Identify the subject and verb. The subject is 'The urban areas' (plural), and the verb is 'are organised'.
Step 2: Determine the correct question form. For a plural subject, the question should start with 'Are'.
Step 3: Examine the options. Option 'a' and 'd' start with 'Are' and correctly use the plural subject. Option 'b' uses 'Do' which is incorrect for this verb form. Option 'c' uses 'Is' which is for a singular subject.
Step 4: Compare options 'a' and 'd'. Option 'a' has a slight grammatical error in the phrasing 'Are the urban areas... organised'. Option 'd' is grammatically sound.
Final Answer: d. Are The urban areas of Canberra are organised into a hierarchy of group centres?
