The correct way to change the direct object ("la pelota") in the sentence "Michael pegó la pelota" to a pronoun is:
Michael la pegó.
In this case, "la" is the direct object pronoun for "la pelota."
The other options listed are incorrect. Here's a brief explanation of why:
- Michael pególo. (Incorrect: "lo" is for masculine nouns, but "pelota" is feminine)
- Michael pególa. (Incorrect: "la" is the correct form, but object pronouns are placed before the conjugated verb)
- Michael lo pegó. (Incorrect for the same reason as above; "lo" is also for masculine nouns)
Therefore, the only correct transformation is Michael la pegó.
