What does dominant-pole compensation do?
Answer: B
It deliberately moves one pole down so the gain has fallen to unity before any second pole contributes phase, guaranteeing a wide margin at the cost of bandwidth. Pole-zero cancellation is a different and more delicate approach, poles cannot be moved above the unity-gain frequency at will, and the low-frequency gain is left intact. Making one effect deliberately dominant so the others need not be controlled precisely is a robust strategy well beyond amplifiers.
