This from PGJC Mock Exam Engine,

Which of these statements concerning the collection interfaces are true?

1.Set extends Collection
2.All methods defined in Set are also defined in Collection
3.List extends Collection
4.All methods defined in List are also defined in Collection
5.Map extends Collection

I know 5 is a wrong ans and 1 and 3 are correct but I am not sure what will be the correct third choice as 2 and 4 both sound wrong to me. Please advise.

Thanks
Sashi
