Explanation: If \(0 < y < 1\), as \(y\) increases: i. \(y^2\) increases, so \((1-y^2)\) decreases. ii. \((y-1)\) increases (since the slope is 1). iii. \(y^2\) increases, so \(\frac{1}{y^2}\) decreases. \(\therefore\) Only \((y-1)\) increases as \(y\) increases. The provided answer is C, which is II only.
