On the Grammarly website, they have the following sentence:
You can upload a document which size is under 4 MB
As a fan of irony and grammar, I'm curious as to whether the bolded portion is grammatically correct. It sounds really awkward, and I've honestly never seen anyone use that phrasing. I would've opted for one of the following:
You can upload a document whose size is under 4 MB
You can upload a document which has a size of less than 4 MB
You can upload a document with a size under 4 MB
You can upload a document smaller than 4 MB
Is their version acceptable?
