    A) It is smaller.
    B) The answer depends on how fast they are moving.
    C) They are equal.
    D) It is larger.

    Impulse is the force multiplied by the time for which that force acts.
    In this case, what can you say about the force of object 1 on 2 and object 2 on 1?
    What can you say about the time for which these 2 forces act?

    In conclusion, what can you say about the 2 impulses?

    The force is the same and the time in the same; therefore, the impulse on each object is the same.
