c) =40Kg
Step-by-step explanation:
To find the answer we have to put all the options in the same unit, so we are going to use Kg.

<u><em>Observation:</em></u> 1 g = 0.001 Kg, 1 g= Kg
This number is very small so it's no suitable for weighing on an ordinary bathroom scale.
- b)
This value is already in kilograms,

- c)
Centigrams: cg=
Then,
This value it's suitable for weighing on an bathroom scale.
- d)
Decigrams: dg=
Then,
This value is too big for a bathroom scale. Usually the limit for an ordinary bathroom scale is between 140-150 Kgs.
- e)
Miligrams: mg=
