Option 1 -> The passage mentions the internet is flooded with nutrition information, not that NIN received requests from people.
Option 2 -> The passage explicitly states "it is difficult to find a balanced meal that works for you from the information swirling around you. That's why the National Institute of Nutrition (NIN)...has released a comprehensive guideline" - directly linking the difficulty to the reason for release.
Option 3 -> While NIN operates under ICMR's aegis, there's no mention of pressure; they work together collaboratively.
Option 4 -> No indication in the passage that ICMR wanted to "take over" health responsibility.
Hence, Option 2 -> The passage clearly establishes a cause-and-effect relationship between the overwhelming and confusing nutritional information available online and NIN's decision to release comprehensive, balanced guidelines suited to Indian body types and accessible resources -> correct
