**Choosing the Best Option:**

The best option depends on the context and the overall style of your website. Consider the following:

* **Target Audience:** Who are you trying to reach? (e.g., parents, teenagers themselves)
* **Website’s Tone:** Is your website formal or informal, informative or motivating?
* **Length:** WordPress allows for any length, but sometimes shorter is better for readability.

I recommend starting with Option 1 or 2. If you need to provide more detail or promote a particular aspect, Option 3 or 4 are good choices. Remember to choose something that accurately represents the content tagged with “青少年活動”.
