Look at the circumstances under which Bassanio has come to court Portia. Is he the type of man Portia’s father would have chosen for her? Does he have an unfair advantage in her hints?

I think Portia's father would approve of Bassanio because he chose correctly. Obviously her father was looking for a man of depth and honor, who would respect his daughter, by setting up the casket test in the first place. The theme of worth being derived from within is what seems to be Portia's father was looking in a husband for his daughter.
