Mass and weight are different in physics. Weight is given by a very simple formula: W = m g
m= mass (kg)
g = acceleration due to gravity (in your case 10 m/s^2)
W = weight (N)
W = (110 kg) ( 10 m/s^2) = 1100 kg m/s^2 = 1100 N
N stands for Newtons, the unit of weight or force. Kg(Kilogram) is a unit of mass.
1 kg m/s^2 = 1N
C is the correct answer.
Extra info:
Your mass stays the same regardless of where you are in the universe. Your weight, however, changes depending on the gravitational field at your location. For example, if you are on moon, your mass stays the same, but your weight will decrease by a factor of 6 (moons gravity is 1/6 earth's gravity).
Cheers :)
