**Choosing the Best Option:**

The best option depends on your specific needs and the overall tone of your website. Consider:

* **Who is your audience?** Are they general readers, medical professionals, or researchers?
* **What kind of content do you typically publish?** Is it news, in-depth analysis, or a mix of both?
* **How much detail do you want to provide in the tag description?**

I recommend you choose Option 2 or Option 3 if you want a complete description; Option 5 if your content is varied.
