Explanation:

From Statement I, Sona is 12th from the right end, so Suhail is 10th from right end so (15-10+1) 6th from left end.
From statement II, Arnav is 8th from right end means before changing postions, Suhail was at 8th position from right, so (20-8+1) = 13th from left end

Hence, option 3 is the correct answer.
