Explanation:

• A census includes all in a population, not used here.
• "Sample" is a general term, not a specific method.
• Random selection picks randomly, but here candidates respond voluntarily to ads.
• Voluntary response sampling uses self - selected participants (responding to ads/ publicity), matching the method.

Answer:

D. voluntary response
