The only correct answer is 0.
There are 8
statements
in the estimated execution plan, but no queries.
From BOL:
A query is a request for data that is stored in SQL Server.
Query Fundamentals
There isn't a single statement in the batch that does a request for data, hence no queries.

Sorry, no. 0 is the correct answer, as each element of this question is a statement, not a query.
As above, BOL defines a query as a request for data, not a request to set an environment variable.
Poor question today.

Note to developers:
CAST(SUBSTRING(CAST(FLOOR(NULLIF(ISNULL(COALESCE(1,NULL),NULL),NULL)) AS CHAR(1)),1,1) AS INT) == 1

I second guessed that the question meant statements as opposed to queries as otherwise it made no sense at all. I also second guessed that it wouldn't be 9 as I'd assumed so I ran a trace. I've been unable to capture the SET QUOTED_IDENTIFIER statement in a trace using SQL:stmtcompleted event at all. This applies whether I set it on or off, as part of a transaction or out of it, as part of a bunch of set statements or on its own. Even though I can't capture the statement, running it does have the expected impact. It may not have much in the way of practical implication but there is something interesting going on with the SET QUOTED_IDENTIFIER statement which the question has highlighted.

I didn't understand the question at all, so guessed. Having read the explanation I was none the wiser.
So I tried it, and the execution plan was empty.

to be quite honest, i'm at a bit of a loss about what to make of this question.
I assumed the question meant statements and not queries, so traced it using profiler, for statement started.

The profiler shows Read 0
This is the most wrong and useless qotd in the history of ssc.
