  2. (b) 2 and 3 only
  3. (c) 1 and 3 only

Why the answer is (d)

• Lipsticks (1) have been found to contain traces of lead from pigments, a concern flagged by the US FDA and Indian studies.

• Brominated vegetable oil (2) was used as an emulsifier in citrus soft drinks; it is banned in the EU and Japan and was banned in the US in 2024.

• Monosodium glutamate (3), the flavour enhancer associated with 'Chinese restaurant syndrome', is controversial though FSSAI permits it with labelling.

• All three pairs are correctly matched.

• Hence 1, 2 and 3, option (d).

Why the other options are wrong

(a) 1 only
Pairs 2 and 3 are also correct.
(b) 2 and 3 only
Pair 1 (lipstick–lead) is also correct.
(c) 1 and 3 only
Pair 2 (soft drinks–BVO) is also correct.
