For the first one- B. Magma (I don't think there is a need to explain this..)

Second question- C. ability to burn 
A physical property doesn't change a material's actual composition, just the way it looks, and/or it can be measured without changing a material's chemical composition. Melting point, hardness, and density apply to this, while the ability to burn does not.
