**Recommendation:**

I would recommend **Option 2 or 4**, depending on the specific content and goals of your blog post. Option 2 is a good all-around choice, while Option 4 is better if you want to optimize for search engines. You can also tailor it further based on the content of your post–if the article focuses more on specific problem behaviors, for example, Option 3 may be better.
