Read the fourth stanza from "Mutability.”It is the same!—For, be it joy or sorrow, The path of its departure still is free: Man’s yesterday may ne’er be like his morrow; Nought may endure but Mutability.

The stanza says that whether a person feels joy or sorrow, that feeling can pass, and that yesterday may be unlike tomorrow. Its final line says that nothing endures except change. This supports choice C, “Emotions are ever changing,” rather than the broader claim that everyone experiences both emotions.
