Engineers tested four battery designs' capacity retention (% of original) after 500 charge cycles, at two ambient temperatures: Battery I, 92% (20°C), 81% (40°C); II, 88%, 86%; III, 95%, 70%; IV, 84%, 83%. The team argued that for hot-climate use, design choice should prioritize <em>temperature stability</em> (small drop) rather than peak capacity. The data most uniquely supporting this nuanced claim is ______
Which choice most logically completes the text using the data above?
- A
Battery III's highest 20°C capacity (95%).
- B
the average capacity across batteries.
- C
Battery I's 20°C capacity of 92%.
- Dcheck_circle
Battery IV: lower 20°C capacity (84%) but only a 1-point drop at 40°C, versus Battery III's 25-point drop despite the highest peak.
Explanation
The nuanced claim is that <em>peak</em> doesn't predict hot-climate performance. Choice B uniquely demonstrates the rank reversal: Battery IV looks worse on peak but maintains capacity; Battery III looks best on peak but degrades sharply. Choice A actually supports the rejected "highest peak" view.
