100 Kilograms is correct. subs got it first
Pounds are a measure of weight, which is decided by gravity.
Kilograms are a measure of Mass, which is constant. Hence a 100kg object on Earth is still 100kg on the Moon.

Checking in as a sub. Pounds and kilograms are both units of measure using different measuring systems. Both are used for measuring mass or weight and can be converted back and forth betwen the two (pound vs. kilogram) with simple math. Yes, mass is constant no matter which measuring system is used, but the effect of gravity on that mass changes depending on the size of the various masses involved. Whether measured using pounds or kilograms, the weight will change on the moon because there is less gravitational pull there, which as I remember it is approximatley 6/10 that of Earth making the correct answer 60 kg making Thornhappy correct. Here is my source, and a quotation from that site.

Mass is defined as the amount of matter in an object.
Mass is different from weight, which is defined as a measure of the force of gravity acting on an object.
A scale is a device to measure mass.
There are two types of scales:
A calibrated scale has a bar at the top that can be read in a manner similar to that of a ruler.
A two-arm balance is used by adding weights to one side of the scale until this amount is equal to the mass of the object being weighed on the other side.
Mass is measured according to the same systems used for measuring length. The standard U.S. Customary Unit for measuring mass is the pound. The standard unit of the Metric System is the kilogram. The table below shows these two systems of measurement.
