To determine which sentence requires semicolons instead of commas, we need to identify if there are complex lists or if there are parts that can lead to confusion with the use of just commas.
The only sentence that needs semicolons instead of commas is:
D. "The high-school softball team are the pitcher, the catcher, and an outfielder; the high-school softball team is led by captains Marisa Martino, Rachel Morrison, and Lisa Fiore."
In this case, if the “the high-school softball team” part was included multiple times with additional lists or clauses, semicolons could clarify the structure. However, as written, the sentence D is also combined awkwardly.
Otherwise, if there's no major complex list, the other sentences are fine as written. Therefore, no specific sentence from the options you provided actually requires semicolons, but if restructuring D, a semicolon after the player's titles will work if used for extra clarity and separation.
