Well, you've got a problem there, because "kilogram" is not a unit
of weight or force.  It's a unit of mass, and it has different weights
in different places.

On the moon, 13 pounds 7 ounces is the weight of about
36.8 kilograms of mass.

On Mars, 13 pounds 7 ounces is the weight of about
16.1 kilograms of mass.

On Earth, 13 pounds 7 ounces is the weight of about
6.09 kilograms of mass.

The answer is b: step 2.
