Correct answer: D

To determine the truth value of ¬p ∨ (p → q) given that ¬p → q is true, we analyze the logical implications. The premise ¬p → q is equivalent to p ∨ q. This means at least one of p or q must be true.\nConsider two scenarios satisfying the premise:\n1. If p is True and q is False, then ¬p → q becomes False → False (True). However, the target proposition ¬p ∨ (p → q) becomes False ∨ (True → False), which simplifies to False ∨ False = False.\n2. If p is True and q is True, then ¬p → q becomes False → True (True). The target proposition becomes False ∨ (True → True), which simplifies to False ∨ True = True.\nSince the target proposition evaluates to both False and True depending on the specific truth values of p and q (while satisfying the initial condition), its value is not fixed. Therefore, it cannot be determined solely from the given information.
