    During alpha-beta search, a branch can be pruned as soon as ____.

    a)
    alpha becomes zero
    b)
    alpha becomes greater than or equal to beta
    c)
    beta becomes negative
    d)
    the branch reaches depth one

    Explanation

    When alpha ≥ beta, the opponent would never allow play to reach this branch, so its remaining moves cannot change the decision.
