A.
Access path analysis is not performed for SQL statements.
B.
SQL structure analysis is not performed for SQL statements.
C.
SQL Profile recommendations are not generated for SQL statements.
D.
Staleness and absence of statistics are not checked for the objects in the SQL Tuning
Advisor.
Answer C is correct!
Oracle Doc says:
17.3.2 Tuning Options
SQL Tuning Advisor provides options to manage the scope and duration of a tuning task. You can set the scope of a tuning task either of the following:
Limited
In this case, SQL Tuning Advisor produces recommendations based on statistical checks, access path analysis, and SQL structure analysis. SQL profile recommendations are not generated.
Comprehensive
In this case, SQL Tuning Advisor carries out all the analysis it performs under limited scope plus SQL Profiling. With the comprehensive option you can also specify a time limit for the tuning task, which by default is 30 minutes.

@Hendrik, you are correct.
However I would suggest reading (the same information) …
http://oracle.su/docs/11g/server.112/e10821/sql_tune.htm#i34782
If the limited option is chosen, the SQL Tuning Advisor produces recommendations based on statistics checks, access path analysis, and SQL structure analysis. SQL profile recommendations are not generated.
