How can you say that some pens can never be holder???.......is it given in the statement?....not..its not given which indicates that its just a possibility.....so you can not say that it can never occur...yes its not true but it can be...which exactly we don't know that it will occur or not.....But the 3rd conclusion is: No pen is holder, we also can not say that this statement is true because its not mentioned in the statement...yes so one from both will occur viz. either I or III....

Note:

Some+No = Either Or (Provided we do not know the relation between two elements)
