The literal meaning of the analogy "My pride in myself is now stronger than my fear of failure once was" can be best interpreted as:
D. The fear of taking a math test has gone away and the author is now a much stronger person than before.
This option captures the essence of the analogy, which compares the current strength of the author's pride to the previous strength of their fear, suggesting that the fear has diminished and the author has grown stronger in self-confidence.
