what is the meaning of o in the code following... does it point to status in the foreach loop.

foreach (var status in statuses)
                if (excludeStatuses.Exists(o => o.Equals(status)))
                    badStatus = true;

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

its looping through each instance of the object in statuses

then it is looking in (most likely) a list to see if that current object exists in it if it does then it sets the bool badStatus to true.
o is the same type as that of the excludeStatuses collection.  I'm assuming it's of type Status.

So, if this excludeStatus collection contains a status element that matches the status value being evaluated, then set badStatus = true.
Yes, each status from statuses is searched in excludeStatuses collection. You can read this as: if status from statuses exists in excludeStatuses it's bad status.
