Read the sentence. Allie considered it carefully, and ______ decided to train for the marathon herself. Which type of pronoun would best complete the sentence?

The blank is the subject of the verb “decided,” so it needs a subjective pronoun such as “she”: “Allie considered it carefully, and she decided to train for the marathon herself.” “Herself” is reflexive here, but it appears later in the sentence and does not fill the blank.
