Final answer:
The correct change for proper comma usage in the sentence is the insertion of commas before and after the nonessential clause 'who just graduated from high school', resulting in option 1 being the right choice.
Step-by-step explanation:
The correct change to be made to the sentence when editing for correct comma usage is option 1, which reads: "Kayla, who just graduated from high school, wants to attend the University of Houston.". This is because "who just graduated from high school" is a nonessential clause that provides extra information about Kayla. It should be set off by commas before and after the clause. Now, let's review a few sentences with missing commas or to omit incorrectly placed commas.
