**Key considerations when choosing the right description:**

* **Target audience:** Consider who you are writing for. Are they legal professionals, the general public, or a specific ethnic group?
* **Level of detail in your content:** If you’re going to publish very in-depth articles, a more detailed description will be appropriate.
* **SEO:** While the description doesn’t have direct SEO impact as the post title, it is important that its language correctly reflects the search intent around this keyword.
* **Character limits:** WordPress tag descriptions might have character limits, so choose the option that best fits within those constraints.

I recommend choosing either Option 2 or 3, depending on the depth of your content. For more general content, Option 2 would be sufficient. For more detailed content, Option 3 is superior.
