Answer:
D. "The surf dances" reinforces the happy feeling of the poem because dancing often makes people happy.
Explanation:
The question asks for a phrase with personification, which means a non living object is described so that it seems like it is alive. "The children play" is not a use of personification because children are, obviously, living. In contrast, "The surf dances" is an example of personification because the surf, or the ocean, is not alive. So, either B or D could be the correct answer. B says that "dancing requires a great deal of physical effort", but that isn't what the poem is about. D says "dancing often makes people happy", and the poem's mood is happy, so it most clearly contributes to the overall meaning of the poem.
