Which one of the first order predicate calculus statements given below correctly expresses the following English statement? Tigers and lions attack if they are hungry or threatened.

The given statement can be explained as follows: If x is lion or if it is hungry or it is threatened, x will attack P(x) = lion (x) v tiger (x) Q(x) = hungry (x) v threatened (x) R (x) = attacks (x) P(x) $\rightarrow$ (Q (x) $\rightarrow$ R (x)) Expanding all, ∀x[(lion(x) ∨ tiger(x)) → {(hungry(x) ∨ threatened(x)) → attacks(x)}]
