The correct response is: Weight is the product of the mass and the acceleration due to gravity.
In mathematical terms, this relationship is expressed as:
\[ \text{Weight} = \text{Mass} \times \text{Acceleration due to gravity} \]
or
\[ W = m \times g \]
where \( W \) is weight, \( m \) is mass, and \( g \) is the acceleration due to gravity (approximately \( 9.81 , \text{m/s}^2 \) on Earth).
