Answer:

A and C are proportional relationships.

Step-by-step explanation:

Recall that a "proportional relationship" has no constant term.  Thus, we eliminate Answers B and D immediately.

Answer A represents a proportional relationship:  y varies directly with the square of x.

Answer C also represents a proportional relationship:  y varies directly with x.
