"Under what form would our government operate?" Is this correct phrasing? [closed]

In this sentence

Under what form would our government operate?

I am wondering whether Under what form or In which/what form would be the correct phrasing, and I realised that I can't find the answer. Does anyone have any ideas?

Solution 1:

It looks like either of them could be used, but according to Gngram in what form is the most common, while under what form is the least used. If you think of a sentence like

Our government will operate under this form for a few years.

it does look less common than

Our government will operate in this form for a few years.

Gngram again strongly agrees.

Having said that, when I did a search on Google I did find some examples of occurrences of The Government operates under.... Here is one:

Local government in England operates under either a one tier system...

However, if you wish to be on the safe side, maybe stick with "in".
