Answer:
Table (4)
Explanation:
If data in the given tables show the proportional relation then they will follow the rule,
y = kx
k =

where 'k' = proportionality constant
From table (1),
k =
= 2
k =

But 2 ≠ 1.5
So the data in the table (1) is not proportional.
Table (2)
k =

k =

Therefore, data in the table is not proportional.
Table (3)
k =
= Not defined
k =

Data is not proportional.
Table (4)
k =

= 3
k =

3 = 3
Therefore, data given in table (4) represents the proportional relationship.
