    D) 0°

    Explanation:

    If vectors A and B add up to vector C, then vector C must start where A starts and end where B ends.

    Since we also know the magnitudes of A and B add up to the magnitude of C, then A, B, and C must be inline with each other.

    Therefore, the angle between A and B is 0°.
