B — "Some springs are hooks." — This is the starting statement establishing a partial relationship between springs and hooks.
C — "All springs are wires." — This places springs entirely inside the category of wires.
F — "All wires are springs." — This makes wires and springs co-extensive (each is the other). This, together with C, implies that wires and springs are the same set, which affects the relationship with hooks in B.
Thus, B, C, and F are logically connected in terms of categorical logic. Even though real-world plausibility isn’t considered here, the question groups these because of their definitional overlap and logical linkage.
