Answer:
Another Half note
Explanation:
The following information will help you in the future with any music questions based off of a measure in 4/4 time-
Quarter note = 1 beat (4 quarter notes = full 4/4 measure)
Half note = 2 beats (2 half notes = full 4/4 measure)
Whole note = fills up the whole measure, no matter the time (1 whole note = full 4/4 measure)
It might be helpful to write that down.
So, if you have a half note (which equals 2 beats), in order to make a complete measure, you need to add 2 more beats.
Therefore, adding a quarter note won't work (you would have to add 2), adding a whole note won't work, and adding a dot won't work. You could, however, add a half note, and then the measure will be complete.
I hope this helps! Have a lovely day!! :)
