To understand the positions in a Venn diagram involving two sets, we can label the sections of the Venn diagram as follows:
- Section I (Only in Set A): Elements that are exclusive to Set A but not in Set B.
- Section II (Overlap - A ∩ B): Elements that are in both Set A and Set B.
- Section III (Only in Set B): Elements that are exclusive to Set B but not in Set A.
- Section IV (Outside of both sets): Elements that are not in either Set A or Set B.
In the scenario you provided:
- Set A contains 1 (and possibly 2),
- Set B contains 3 (and possibly 2),
- The overlap (A ∩ B) contains 2,
- The number 4 is outside of both circles.
Given that \( k \in A \cap B \), the most specific location of \( k \) on the Venn diagram is in Section II, which represents the overlap between Set A and Set B.
Thus, the answer is II.
