Answer: Option C

Step-by-step explanation:

We know that the the ratio is 5:7

this means that if the object in the Earth weights 7kg, in neptune it will weight 5 kg in Neptune

This means that the weight in Earth is related to the weight in Neptune by:

We = 5/7Wn

then, if a person weights 150 punds in Earth, we have that:

We = 150 pounds = 5/7*Wn

Wn = 7/5*150pounds = 210 pounds

the correct option is option C
