Answer:
B
Step-by-step explanation:
B has a proportional relationship between "a" and "b" as when you divide corresponding "b" values by their respective "a" values they will always give the same thing, that being 1.25 for this situation
[tex]25/20=1.25[/tex]
[tex]30/24=1.25[/tex]
[tex]40/32=1.25[/tex]
this can also be done in reverse by dividing "a" values by their respective b" values to get the same value every time
Hope this helps
