The correct response is A: describe the loneliness the speaker feels when she feels far from her parents.
In the third stanza, the speaker uses metaphors of her father as "earth" and her mother as "sea" to convey a sense of grounding and support from her parents, while simultaneously expressing a disconnect or distance ("Close to home, yet a bit far"). The metaphor of being "an island" emphasizes the solitude the speaker experiences, suggesting that despite having a connection to her parents, there are moments of emotional isolation where she feels separated from them.
