The answer is “Identity”. (Or A)
Reason: The speaker has found himself realizing that he needs to find his identity.
We know that 'migrate' means to move. So since that, we need to add the -ing, and we know that we end up with the meaning "moving".
So migrating means moving from one place to another.
Contrast is the right answer for the question
A metaphor is comparing two unlike objects without the use of the words like or as. Metaphors are usually symbolic. An alliteration is a group of words that have similar letters or sounds. Personification is giving an inanimate object the characteristics that a person would have. Sarcasm is the use of irony to mock. You must decide from here.
