Nanotechnology allows the manipulation of atoms and molecules to form structures on the scale of nanometers, or billionths of a meter. These "nanostructures" are now being used to augment already-extant goods. For example, to prevent the stench associated with athletic apparel, some fabrics contain nanostructures that soak up and neutralize odor-causing hydrocharbons, and then release them when washed. Scientists' insight into nanostructures is still nascent; thus, ________________________.
a. studies on reinforced fabrics are getting underway
b. incremental improvements are being made to current products
c. the future utility of nanotechnology is uncertain
d. the effect of a new fabric incorporating nanostructure remains unclear
답은 안 드릴게요.
해설집 봐도 이해가 잘 안되고요.
이 지문 앞뒤 일관성이 떨어져 보이는데 결론을 찾으려니 힘이 드네요.

마지막 문장의 전반부에서 이미 예시(섬유 분야)를 끝낸 상태에서 일반론으로 돌아온 걸로 판단하고
c로 갈 거 같음.....
