What is the unstated premise in the following syllogism? No one is happier to be at this wedding than I am, so my aunt is not happier to be here.

A) My aunt is at this wedding.
B) There is a wedding.
C) Two people are getting married.
D) I have an aunt.
E) My aunt is someone.

The unstated premise for the conclusion to make sense is that the aunt is included in the category of "no one," meaning she is considered as part of the group being referred to. This is directly related to the statement about happiness at the wedding, making E the correct choice.
