Sodium chloride is the chemical name for salt and is composed of sodium and chlorine, so it is a compound.
The law of conservation of matter basically states that matter can’t be created or destroyed, only changed in form, so you can rule out any option that mentions destroying or creating matter. That leaves only option A. Atoms cannot be created or destroyed by chemical reactions.
Buoyancy is a condition in which a physical body's average density is equal to the density of the fluid in which it is immersed.
The buoyancy offsets the force of gravity that would otherwise cause the object to sink (if the body's density is greater than the density of the fluid in which it is immersed) or rise (if it's less). An object that has neutral buoyancy will neither sink nor rise.
