Java ArrayList of Strings: Identifying the Incorrect Code

Tom wants to implement an ArrayList of Strings. Which one of the following lines of code cannot satisfy his requirements?

OA List strList = new ArrayList(); OB ArrayList strList = new ArrayList(); OC List<> strList = new ArrayList(); OD ArrayList strList4 = new ArrayList<>();

OC - List<> strList = new ArrayList(); (syntax error - missing type parameter for List)
