Concept:The error is caused by the incorrect use of the preposition "for" before a base verb.
Explanation:In part A, the phrase "for ensure" is grammatically wrong.
After "for", a gerund (-ing form) should be used, or we should use "to" with the base verb.
So the correct form is either "to ensure" or "for ensuring".
The correct sentence would be: "The Food Safety and Standards Authority of India (FSSAI) recommends QR codes on food products to ensure accessibility for visually impaired individuals, promoting informed consumer choices and addressing rising non-communicable diseases."
Parts B, C, and D are correct.
Hence, the error lies in part A.
Answer:Option A
