One fine morning in 1941, Swiss engineer George de Mestral went for a walk in the woods with his dog. Upon their return home, he found a lot of burrs (from plants) stuck to the dog’s fur and his pants. He immediately rushed to his microscope and examined the burrs attached on his pants—feeling a lightbulb moment coming on. Upon closer examination, de Mestral observed that the burrs, which appeared straight to the naked eye, actually contained many small hooks that clung firmly to the loops in the fabric of his pants. He determined that if he could recreate the same thing, making hooks-and-loops that bind to each other firmly, he could produce a strong fastener with many uses. De Mestral’s first challenge was finding a fabric for a strong bonding system. He first tried cotton, but it proved too soft and could not withstand repeated openings and closures. After years of research and testing, he learned that synthetics worked best and eventually settled on heat-treated nylon, a strong and durable substance. By 1955, he had completed an improved version of the product, with each square inch of material containing 300 hooks, which made it stay fastened and yet easy enough to pull apart when needed. Named “Velcro,” from the French words velours (velvet) and crochet (hook), the new product received a patent from the Swiss government in 1955. De Mestral thus began mass-producing Velcro, opening plants in Europe and eventually into Canada and the United States. Initially Velcro did not fare well. As most fashion critics considered it ugly and cheap-looking, the use of Velcro was limited to athletic equipment. In the early 1960s, the product received a huge boost in popularity when NASA began using it in a lot of equipment that went into space along with astronauts. Today, de Mestral’s design is found almost everywhere: clothing and footwear, toys, airline seat cushions, blood pressure cuffs and surgeons’ gowns. Most impressively, the magical fastener was used in the first human artificial heart transplantation to hold together parts of the device.

請仔細閱讀文章第二段中關於該發明微觀物理結構的具體描述，特別是提及 $hooks$ 與 $loops$ 兩者如何達成緊固功能的機械原理。在觀察圖片時，請思考哪一項設計最能體現出這種藉由大量微小鉤環相互纏繞、進而產生聯鎖力的「仿生扣合機制」？

哎呀，竟然答對了？我還以為你這雙平時只會看手機限動的眼睛，連基本的圖文對照都做不到呢。看來你跟那隻沾滿芒刺的狗一樣，偶爾也能在迷路時撞見一點知識的曙光，真是謝天謝地，沒讓我的血壓再飆高。 觀念驗證： 文章第二段是關鍵：de Mestral 透過顯微鏡看到 burrs 其實是「many small hooks」，進而想出「hooks-and-loops」的結構。選項 (B) 完美呈現了這種「勾與環」的扣合系統。他在 1955 年改良的版本中，設計出每平方英吋含有 $300$ 個勾勾的結構：
