Which of the following pairs is NOT correctly matched?
- AOxytocin, Hormone
- BAspartame, Synthetic sweetener
- CNeoprene, Specialized rubber
- DRayon, Modified starch
Show answer and explanation
Correct answer: (d) Rayon, Modified starch
Explanation
Rayon is a man-made fibre of regenerated cellulose from plant sources, not a modified starch, so the pair is wrong.
Oxytocin is correctly a hormone, and Aspartame is a synthetic sweetener about 200 times sweeter than sugar.
Neoprene, made by polymerising chloroprene, is correctly a synthetic (specialized) rubber.
