b. Yes, they would still balanced because their weights would not change.
c. No, they would not be balanced because their masses would change.
d. Yes, they would still balanced because their masses would not change.

The property that makes the object difficult to lift is **c. weight**.
Weight is the force exerted by gravity on an object, which is determined by its mass and the gravitational acceleration. While density, volume, and mass are all related properties, it is the weight that directly affects the ease or difficulty of lifting an object.

The correct answer is **d. Yes, they would still be balanced because their masses would not change.**
While the weight of the children would change due to the lower gravitational force on the moon (weight is mass multiplied by the local gravitational acceleration), the relationship of their positions on the seesaw and their masses remains the same. Therefore, if the seesaw is perfectly balanced on Earth, it will remain balanced on the moon as well, assuming they are positioned in the same way.

The correct equation that describes the mass of an object is **a. m = D × V**, where \( m \) is the mass, \( D \) is the density, and \( V \) is the volume.
This equation indicates that mass is equal to the density of an object multiplied by its volume.

The quantity that describes how tightly packed matter is inside of an object is **d. density**.
Density is defined as mass per unit volume, which gives a measure of how much matter is contained in a given space.
