Answer: B 
Step-by-step explanation:
From the given table
When x changes from 1 to 2 , value of y changes from 6 to 4
The multiplicative rate of change=
Similarly we can check
When x changes from 2 to 3 , value of y changes from 4 to 
The multiplicative rate of change=
When x changes from 3 to 4 , value of y changes from
to 
The multiplicative rate of change=
Therefore, the multiplicative rate of exponential function = 
50 =2×5×5
125=5×5×5
Hoghest common factor = 5×5
=25
