Duplicate posts in an infinite feed

An infinite feed loads pages with ?page=3&size=20. New posts get added at the top while users scroll, and they see duplicate items. What is the better design?

A.Use a bigger page sizeB.Reload the whole feed on every scrollC.Use cursor-based pagination, where the client sends the id or timestamp of the last item and gets the items after itD.Cache every page on the device for 24 hours, so the same page number always returns the same items while the user scrolls
