Option 1 : Conclusion I and either II or III follows

The least possible venn diagram is as shown below:

Conclusion:

1) Some boxes are Pens – True (All pens are boxes)

2) Some boxes are balls – False (it is possible but not definite)

3) No box is ball – False (it is possible but not definite)

Here, conclusions II and III form a complementary pair.

Hence, only conclusion I and either II or III follows.
