3, 0, 1

6, 5, 9

8, 7, 6

Answer : Option B

Explanation :

i) The number 5631> 1 and the number of digits in the integral part are 4.
Therefore, the characteristics of the logarithm are 4-1 = 3,

ii) In the number 5.678, the number of digits in the integral part = 1.
Therefore, characteristics of the logarithm are 1-1 =0

iii) In this case, the number of digits in an integral part of the number 56.23 are 2.
Therefore, the characteristics of the logarithm = 2-1 = 1
