Which normal form does this table violate?

Question

Consider this table:

   +-------+-------+-------+-------+  
   | name  |hobby1 |hobby2 |hobby3 |  
   +-------+-------+-------+-------+   
   | kris  | ball           


        

Answer 1

If any of the columns in the table accept nulls then then the table violates first normal form. Assuming no nulls, @dportas has already provided the correct answer.
