Solution

The correct options are
A
Low melting point

B
Combustibility

C
Isomerism

D
Low boiling point

All of these are correct in this context. Methane, ethane, propane and butane are gases at room temperature. They have low melting and boiling points. Butane and pentane also have at least two isomers each. All these are combustible too.
