Answer
Answer:
No Change Is Needed
Brief Explanations:
In English grammar, when listing items (here, "reading", "writing", "painting"), the serial comma (the comma before "and") is optional in American English. The original sentence "She enjoys reading, writing and painting in her free time." is grammatically correct.
- The second option "She enjoys reading, writing, and painting In her free time." has an incorrect capitalization ("In" should be "in").
- The third option "She enjoys reading, writing, and painting, in her free time." has an extra comma after "painting" which is not needed as "in her free time" is a prepositional phrase modifying the whole action (not an additional item in the list).
- The fourth option "She enjoys reading writing, and painting, in her free time." is missing a comma between "reading" and "writing" which makes the list unclear (it seems like "reading writing" is one item instead of two separate activities).
