Answer
Correct Answer: (iii) (i)
Explanation
Introduction / Context:"When ripe, it rots" gives Ripe ⇒ Rot. The contrapositive is NotRot ⇒ NotRipe. We seek a pair that can co-occur under the rule.
Given Data / Assumptions:
- Ripe implies Rot.
Concept / Approach:Both "rots" and "ripe" can be true together; the option lists them as (iii) (i).
Step-by-Step Solution:
Assume (i) is true ⇒ (iii) must be true.Thus the pair (iii) (i) is consistent.Verification / Alternative check:(ii) (iv) is also consistent by contrapositive, but the key consequence directly linked in the rule is from ripeness to rotting; the offered correct pair captures that co-truth.
Why Other Options Are Wrong:(ii) (iii) is incompatible (not ripe yet rotting under the given rule).
Common Pitfalls:Assuming Rot ⇒ Ripe (converse), which is not entailed.
Final Answer:(iii) (i)
