Correct Answer: 3
Solution :
Take any consecutive odd numbers i.e., 1, 3, 5 or 3, 5, 7 etc.
Their sum = 1 + 3 + 5 = 9 which is divisible by 3.
Again, the sum = 3 + 5 + 7 = 15 which is divisible by 3.
So, the sum of three consecutive odd numbers is always divisible by 3.
Hence, the correct answer is 3.
