Answer:
Step-by-step explanation:
1) The first option is only 1 quarter note and 2 eighth notes, which is 4 eighth notes. That is 1 more eight note than needed to complete the bar.
2) The second option is an eighth rest and an eighth note, which is 1 eighth note less than needed to complete the bar.
3) This option is the only option that provides us with 3 eighth notes, which is sufficient to complete the bar.
4) The fourth option is wrong as there are only 9 eighth notes in the initial question.
