During which evolutionary phase does the most dramatic mass loss for a Sun-like star occur?

Answer

The Red Giant and subsequent Asymptotic Giant Branch (AGB) phases

The most significant mass ejection occurs after the star exhausts core hydrogen and evolves into a red giant, leading to much stronger stellar winds and episodic ejections during the AGB phase.
