    Not C, because the picture shows that vMotion is up and running
    Not D, because the picture shows that there are clearly enough host memory and host CPU resources.
    The link also states:

    A higher threshold makes the cluster a more likely candidate for load imbalance.”

    which makes ‘E’ valid
