The correct response is:
It helps convey the idea that fear and deceit nourish and foster the growth of anger.
In the second stanza, the imagery of watering the wrath with "fears" and "tears," along with nurturing it with "smiles" and "soft deceitful wiles," suggests that negative emotions can contribute to the growth of anger. The metaphor of the tree growing represents how unresolved feelings can develop and become dangerous, reflecting the overall theme of the poem.
