Answer 6

Correct answers: a, b, d

Explanation:

Table names begin with a letter from A to Z, or a to z, can contain the number 0-9 or the dollar ($), underscore (_), and hash (#) signs. Table names may not duplicate the name of any other database object if the same user owns that object.

They are not case-sensitive by default and are created in upper case by default unless otherwise specified. Thus, choices C and E are incorrect.
