Correct answer: B
Concept
A Venn diagram is a graphical notation that represents classes and their relations by spatial regions.
In categorical logic, it helps display the premises of an argument and test whether the conclusion follows. Validity or invalidity is a property of the argument, not of the diagram used to represent it.
Application
Statement (a) describes the representational role: an argument's class relations can be shown graphically.
Statement (b) describes the pedagogical role: making the relations visible can improve understanding.
Statement (c) assigns validity to the diagram itself; the validity judgment belongs to the argument represented.
Statement (d) describes Venn diagrams as a clear notation for class relations.
Cross-check and contrast
(a), (b) and (c) includes the validity-label claim and omits the notation claim.
(a), (b) and (d) includes the graphical-representation, understanding, and notation claims while omitting the validity-label claim.
(b), (c) and (d) includes the validity-label claim and omits the graphical-representation claim.
(a), (c) and (d) includes the validity-label claim and omits the understanding claim.
Therefore, the code containing only the correct statements is (a), (b) and (d).
