Answer:
None of these
Explanation:
Normally, we consider "weight" to be the force due to gravity that an object exerts in the downward direction. It has a positive value equal to the magnitude of "mg". In this instance, it would be ...
... |(10 kg)·(-9.8 N/kg)| = |-98 N| = 98 N
___
However, you're specifically told to use ...
... w = mg
... w = (10 kg)(-9.8 m/s²) = -98 N
This selection is not among those offered.
