Consider the following pairs: Commonly used / consumed materials - Unwanted or controversial chemicals likely to be found in them 1. Lipstick - Lead 2. Soft drinks - Brominated vegetable oils 3. Chinese fast food - Monosodium glutamate Which of the pairs given above is/are correctly matched ?

1. Pair 1: Lipstick - Lead. This is correctly matched. Lead can be present as an unwanted contaminant in some lipsticks and color additives, leading to regulatory limits and consumer concerns. 2. Pair 2: Soft drinks - Brominated vegetable oils (BVO). This is correctly matched. BVO has been used as an emulsifier in some citrus-flavored soft drinks but is controversial due to health concerns related to bromine accumulation, leading to bans or voluntary removal in many regions. 3. Pair 3: Chinese fast food - Monosodium glutamate (MSG). This is correctly matched. MSG is a flavor enhancer commonly used in Chinese fast food and other processed foods. It remains a controversial chemical for some individuals who report sensitivity, although major health organizations generally regard it as safe. 4. Since all three pairs are correctly matched, the correct option is (D).
