Suppose That in the Venn Diagram of the Premises of a Categorical

Suppose that in the Venn diagram of the premises of a categorical syllogism, there is an X in area 4.But in the diagram of the conclusion, the X is on the line between areas 4 and 7.Is the syllogism valid?

A) No, because the Xs are not in precisely the same place in the two diagrams, which is a requirement for validity.
B) No, because proving that something exists in area 4 is not enough to prove that something exists either in area 4 or area 7.
C) Yes, but only if area 7 is unshaded in the diagram of the premises.
D) Yes, but only if area 7 is shaded in the diagram of the premises.
E) Yes, because if something exists in area 4, then necessarily something exists in area 4 or area 7.
