Answer: D

Explanation

Lead is a common impurity found in cosmetic lip products, such as lipsticks, and other cosmetics, such as eye shadows, blushes, compact powders, shampoos, and body lotions. Brominated vegetable oil is a food additive sometimes used to keep citrus flavoring from separating out in some sodas and soft drinks. It’s banned as a food additive in Europe and Japan. MSG, is a glutamate, or salt of glutamic acid, a “non-essential” amino acid. It is a neurotransmitter – transporting messages from one nerve cell to another. Because it is said to enhance flavours, some scientists believe it “excites nerve endings” and exhibits “neuro-excitatory properties”, that is the ability to stimulate neurons. It is commonly used in Chinese fast food. Hence all the three pairs are correctly matched.
