The table that demonstrates a proportional relationship is C. x: 8 | 12 | 40 and y: 2 | 3 | 4. This is because if you divide each x-value by 4, you get the corresponding y-value.

The table that demonstrates a proportional relationship is Option A.
In Option A:
- x increases from 10 to 15 to 40.
- y increases from 2 to 3 to 8.
As x increases, y also increases proportionally. For every increase in x, there is a consistent increase in y. This shows a direct proportionality between the values of x and y.

To identify the table that demonstrates a proportional relationship, we need to check if the ratio of the y-values to the x-values is always the same.
Let's go through each option and calculate the ratio for each table:
A. x: 10 | 15 | 40 y: 2 | 3 | 8
The ratio is 2/10 = 0.2, 3/15 = 0.2, 8/40 = 0.2
The ratio is consistent, so A may represent a proportional relationship.
B. x: 2 | 5 | 6 y: 10 | 20 | 30
The ratio is 10/2 = 5, 20/5 = 4, 30/6 = 5
The ratio is not consistent, so B does not represent a proportional relationship.
C. x: 8 | 12 | 40 y: 2 | 3 | 4
The ratio is 2/8 = 0.25, 3/12 = 0.25, 4/40 = 0.1
The ratio is not consistent, so C does not represent a proportional relationship.
D. x: 4 | 9 | 16 y: 2 | 3 | 4
The ratio is 2/4 = 0.5, 3/9 = 0.33, 4/16 = 0.25
The ratio is not consistent, so D does not represent a proportional relationship.
Therefore, the table that demonstrates a proportional relationship is A. x: 10 | 15 | 40, y: 2 | 3 | 8.
