Answer 2

Answer:

The answer is "D".

Step-by-step explanation:

"B" and "C" are obviously not the answers as they both refer to indirect proportions instead.

"A" could be the answer only if it included "increase" as direct proportion relates to each other both when they decrease and increase. Thus, "A" is not the perfect answer.

"A", "B" and "C" are not the answers as they do not define direct proportion. Thus, "D" – none – is what we have left.
