Here's the definition of "Metaphor" to help out: a figure of speech in which a word or phrase is applied to an object or action to which it is not literally applicable.
We also know that this is from the poem "My Father in the Navy: A Childhood
Memory” by Judith Ortiz Cofer. With this information we can conclude that the answer you are wanting is C, because, the father wasn't really heralding a new day! Hope this helps!
