It's like a question.
Can I sell private label rights for this product?
Ans:[Yes/No].
Yes, means you can transfer PLR rights to your customers. No, means you can't. Your customer can only use it for personal use for their business, they can't resell the product.
Most products don't give you transferrable PLR rights. It's called master PLR and it would be costlier as you can act as the original creator and sell PLR license to your customers.
Most PLR products come with transferrable Master Resell Rights or Resell Rights if there is. Otherwise, PLR products mean you can modify, break down whatever you want to do and sell it to your customers without any resell rights, it would be for personal use only.
Anyway, your PLR license file should have additional details like how you can sell, if you can give away for free or not and so on.
If you are confused, ask the PLR provider what you can do with the product and what you can't do.
