Answer: (B)

Recognizing a root that means light. Lumen/lumin- is tied to light, and the word that best shows that idea is luminous, since it describes something that emits or reflects light and contains the lumin- root. The other options come from different roots: portable comes from port to carry, pathology from path- disease, scripture from scrib- to write. So luminous is the example that demonstrates the light-root.
