Answer:
c.
Step-by-step explanation:
I'd generally say this would depend on what your definition of proportional is, but there's still one clear answer in this case regardless.
Here, a direct proportional relationship will pass through (0, 0), meaning it will not have a y-intercept and y will be 0 when x is 0.
Because b is the y-intercept, C is the answer as it is the only answer that does not have one.
