My thought would be B) gases.
I could be wrong but that's what i'd say
Increasing the temperature of a gas sample means that heat energy is been supplied to the System. When energy is been supplied heat energy is transformed into kinetic energy of the gas molecules.
Therefore kelvin temperature increases means more energy given to the system therefore average kinetic energy of molecules increase.
When the kinetic energy of molecules increase they move about more and take up more space. Hence volume too increases.
Therefore the correct answer is
4) average kinetic energy of molecules increase and volume of the gas sample increases
Explanation:
When an element is displaced by another element in a compound then it is known as a single displacement reaction.
For example, 
is a single displacement reaction.
Similarly when a hockey player has the puck in the corner of the rink. An opposing player muscles him aside and emerge with the puck displays that a single player is displacing a person.
Thus, we can conclude that this situation is most analogous to single displacement reaction.
