The incorrect usage of the singular possessive is found in the following option:
A. Icarus's fate was sealed when he approached the sun.
The problem is that it should be "Icarus' " - if the word ends with "s", you just add the apostrophe, not an additional S. (actually this is disputed, but it's the only problematic option among the options given)
It injects surprise into the story by making a comparison that conveys how well Sean performs in the race.
I hope this helps you
