Explanation:
The principle in the passage is about **functional efficiency and balance** — natural selection doesn’t favor an organ that lasts far longer than the rest of the body because that extra durability has **no survival value**.
Option E presents a **parallel logic**: it’s **not cost-effective** to make one car part so durable that it **outlasts all other parts**, since that doesn’t improve the car’s overall performance.
Both situations describe systems (a body or a car) where **efficiency is optimized at the system level**, not by maximizing the longevity of any single component.
All other options fail to reflect that principle:
(A) is about consumer demand, not internal system efficiency.
(B) discusses compensation, not optimization.
(C) is about production trade-offs, not component balance.
(D) is about imbalance leading to harm, not about efficiency in design.
Hence, E mirrors the natural selection principle most closely.
