Option 1 -> Starts with "while," which requires a main clause before it, making this sequence grammatically incorrect.
Option 2 -> (B), (C), (A), (D) breaks the logical flow - (C) doesn't connect properly after (B) as it completes (A)'s thought about free radicals.
Option 3 -> (B), (D), (A), (C) creates a complete, coherent sentence: starts with the main subject (curcumin), explains its anti-inflammatory effects and what it reduces, then adds the secondary benefit about anti-oxidants using "while."
Option 4 -> Begins with a fragment (D) that lacks a main subject and verb, making it grammatically incomplete.
Hence, Option 3: (B), (D), (A), (C) -> This sequence forms a grammatically correct and logically flowing sentence that discusses both the anti-inflammatory effects of curcumin and the anti-oxidant properties of turmeric, with proper connection using "while" to link the two related but distinct benefits -> correct
