Read the second stanza from "Mutability.”We rest.—A dream has power to poison sleep; We rise.—One wandering thought pollutes the day; We feel, conceive or reason, laugh or weep; Embrace fond woe, or cast our cares away

The stanza lists many different experiences and feelings: we reason, laugh, weep, embrace sorrow, or cast our cares away. This range of contrasting emotions supports the idea that humans experience a broad range of emotions throughout life. Choice C best captures that idea; the stanza does not say that people lose their ability to reason or fail to appreciate their emotions.
