Sorry for the mistake
I thought you are talking about Vit D

For vitamin C, it's definitely uric acid stones as it acidify the urine
but am not sure about the calcium oxalate stones

I rechecked, Davidson's medicine says it causes Oxalate stones "Daily intakes of more than 1 g/day have been reported to cause diarrhoea and the formation of renal oxalate stones". As I said I don't know why for sure.

As for uric acid stones, cranberry juice and vitamine c cause acidification of urine, theoritically this will pricipitate any other acidic substances (including urate) and increase solubility of alkali.

So I guess means the better answer for which stone caused by vitamin C toxicity would be oxalate stone?

Between, this is a question a came across on USMLE Rx. And they had both oxalate and uric acid stone as the questions options.
