Answer: option B is the correct answer.
Step-by-step explanation:
If two variables are proportional, a change in the value of one variable would cause a corresponding change in the value of the other variable. This means that both variables are related by a constant of proportionality, k.
Looking at the given tables,
For table A,
9/3 = 12/4 but not equal to 20/5
The relationship is not proportional.
For table B,
25/20 = 30/24 = 40/32 = 1.25
The relationship is proportional.
For table C,
12/4 = 15/5 but not equal to 24/6
The relationship is not proportional.
For table D,
4/3 = 16/12 but not equal to 9/6
The relationship is not proportional.
