This will not be automatically added, because you copied and entered the product description incorrectly.
If you add a description with html, you need to copy that html code and paste it in the description while it is being displayed in the 'Show editor'.
Hope it is clear to you.

Hi, @vishal681998! This code you're seeing can happen if you're pasting content into the rich text editor box from somewhere else. The rich text editor will pick up on formatting from wherever you copied the content from. You can find more information about the editor in our help guide
I usually recommend creating your content in the editor or using an app like PageFly. An app usually will be easier if you don't have experience with HTML and want to create more complex-looking pages. You don't need to code even without an app, but if you're toggling the HTML view on, I presume that you're keen on learning code.
To remove that you can simply remove the extra space that the snippet defines before you paste the content in. It won't harm your page to leave it, but if you want a bit more help with coding you can check out Hubspot's helpful article to learn some basics. Alternatively, you can find a suitable Shopify Partner in the Experts Marketplace or request a quote by following this guide here.
