Correct option is B
The correct answer is (b) Synthesis of medicines and fibres
Explanation:
• Amines are key intermediates in pharmaceutical and synthetic-fibre (e.g., nylon precursor) manufacture.
• Aromatic and aliphatic amines are used in dyes, drugs, agrochemicals and polymers.
• While nitrogen compounds can be used in explosives, that is not the primary commercial use.
Information Booster:
• Amines serve as building blocks for many active pharmaceutical ingredients.
• They are used in production of surfactants and dyes.
Additional Knowledge:
(a) Explosives — limited/secondary application.
(c) Batteries — amines are not primary battery components.
(d) Stem cell therapy — unrelated.
