**Recommendation:**

I recommend **Option 2** or **Option 3**. They’re both well-rounded and offer a good understanding of what the tag represents and the benefits to the user. Choose the one that best fits the overall tone of your website. If your website emphasizes user convenience, Option 3 might be best. If you want to clearly list the kinds of content the tag covers, Option 2 is a good choice.
