Explanation:

• Statement 1 is incorrect: Trans fat can occur both naturally and artificially.   Naturally-occurring trans fats are produced in the gut of some animals and foods made from these animals (e.g., milk and meat products) may contain small quantities of these fats.  Artificial trans fats are created in an industrial process that adds hydrogen to liquid vegetable oils to make them more solid.  
• Statement 2 is incorrect: India adopted no such targets. Countries such as Bangladesh, India, the Philippines and Ukraine are adopting best-practices to eliminate trans fat.  
• Statement 3 is correct: Trans fatty acids (TFA) could affect cell membrane functions, and may therefore influence peripheral insulin sensitivity and the risk of developing type 2 diabetes.

Hence option 3rd is correct.
