Answer: Option 'B' is correct.
Explanation:
Since we know that "Angle opposite to greater side is smaller or angle opposite to smaller side is larger".
So, ∠AOD is opposite to side 'AD' which is equal to 8.11
Similarly, ∠AOB is opposite to side 'AB' which is equal to 8.
So, ∠AOB>∠AOD
Hence, Option 'B' is correct.
