Correct Answer - Option 3 : Only II follows

The least possible Venn diagram for the given statements is as follows:

DIAGRAM

Conclusions:

I. Some went is exit → False (It is possible but not definite).

II. All exit is entry is a possibility → True (As only a few entry is exit, some entry is exit and some entry is not exit, so it is possible that all exit is entry). The possibility case is as follows:

DIAGRAM

III. Some went is not exit → False (It is possible but not definite).

Conclusion I and III form a complementary pair of some and some not which is a complementary pair of neither-nor case.

NOTE: Complementary pairs for neither-nor case are:

Some + Some not and No + All.

Hence, only conclusion II follows.
