    To answer this question, you must put like-terms together,

    since you can't subtract 5 with - 4i or add 3i to 5

    Right now the question is asking (5 - 4i) + (3 + 2i)

    So you must use commutative property to get (5 + 3) + (2i - 4i)

    So then your answer is ...

    8 - 2i, the third one
