The short answer is 2", that will hold the 250 Kcmil aluminum you would need
for a commercial 200a service. That's why it is the standard.
If this is a service mast you may need 2 1/2 for strength.
The absolute smallest would be 2/0 copper in a 1 1/4 or 4/0 aluminum in a 1
1/2. It is sure a lot easier to get the wire in a 2" for a few pennies a foot
more.

This is Turtle.

Copper would be a 2 inch and Al. would be 2 inch but for certain type wires and
could even get to the 2.5 inch with some Al. wire types. To know the exact wire
type yopu was going to use would be helpful. Yes I know service entrance cable
but other type can be used.

Our local utility specifies 2 1/2" conduit for residential and 3" for
commercial. Must make it pretty easy for the utility crew, YMMV

Hey asshole, do you ever think of taking your head out of your ass and
answering the question? Your name belongs under the definition of
waste of bandwidth.

I'm leaning towards "C" ;-}

If this will be done in compliance with the US NEC then you would need
1&1/2" for copper or 2" for aluminum single phase dwelling service if
the conduit in question is schedule forty or eighty PVC. Many utilities
require schedule eighty PVC for service entry conductors but schedule
forty is allowed for the feeder between the service disconnecting means
and the main distribution panel.
