**Which option to choose depends on:**

* **Your overall site style:** Do you prefer concise descriptions or more detailed ones?
* **Your target audience:** Are they technical and data-focused, or more general readers?
* **The context:** Where will this description be displayed? (e.g., a sidebar with limited space might favor a shorter description)

I recommend option 2 or 4 for a comprehensive understanding of the tag’s purpose, while option 1 is quickest and simplest if space is a premium. You can also adjust these to best suit your specific needs.
