Both of them change in a significant way after their deaths.
Agamemnon even says: <em>“Imagine I and Achilles, wrangling over a girl, battling man-to-man. And I, 1 was the first to let my anger flare. Ah if the two of us could ever think as one, Troy could delay her day of death no longer, not one moment”.</em>
They don't show much anger regarding how they died or the fact that they did. So we can ignore the second and third options. Their change is regarding humility, which is something that they did not possess before they were dead. This eliminates the 4th options, leaving us with the correct answer:
* Both show humility after their deaths.
