Correct answer: c) Return "Network Unavailable (503)" with a helpful message to all requests

Explanation: Maybe not as commonly known to webmasters, but very useful if your site is down! This tells crawlers to come back later, rather than crawling and indexing your "Down for maintenance" pages when you respond with 200 rather than 503.
