Hint: Use the following expression to get a clear idea about weight$\text{weight = mass }\times \text{ acceleration due to gravity}$. It is similar to the equation of force.

Weight is a measure of gravitational attraction towards an object. It depends on the object and the medium.
$\text{weight = mass }\times \text{ acceleration due to gravity}$
This is similar to the force.
$\text{Force = mass }\times \text{ acceleration}$

Hence both have the same units. Newton is the SI unit of force. Therefore, Newton is the SI unit of weight.

So, the option (D) is correct.

The weight of an object will vary according to the gravitational force experienced by the object. That’s why we are experiencing less weight on the moon, since the gravity on the moon is about $1/6th$ of earth. The weight is a vector quantity.
