    You are correct.

    Newton (N) is a measure of force.

    Also force F is the product of mass (m) and acceleration (a). Unit of mass in SI/mks is kg, and unit of acceleration is m/s2 or units of force are kg-m/s2.

    The definition of 1 N is 1 kg-m/s2.

    In fact, choice (c) gives the fundamental units for Newtons, so choice (b) is really the same. So (d) would be correct.

    when you typed "kg-m/s^s" does this "-" mean minus or multiplying?

    When applied to units, that is a commonly used notation to indicate multiplication.
