Answer:
Option C, sugar, water, oxygen
Explanation:
Force of attraction leads to closer placing of atomic particles in any element or molecule. The higher the force of attraction, the more compact is the arrangement of the atomic particle.
Thus, in a solid the atomic particles are closely packed followed by a liquid and then a gas.
As we know sugar is solid, water is liquid and oxygen is gas.
Thus, forces of attraction between molecules of sugar will be the highest followed by water and then oxygen
Hence, option C is correct
B water at 99c since it is the hottest
