3 (horizontally)
I do not think it is easy to explain this answer.
"Definition of direct variation. 1 : mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other."
The answer is D
All of the other relationships are consistent.
A is x × 3
B is x × 4
C is x × 2
D is x × 2 then 3 then 4.
D is not a direct variation.
