Answer: Option (C) is the correct answer.
Step-by-step explanation:
When a substance changes from solid state to liquid state then this is known as melting of substance. Whereas when a substance changes from liquid state to gaseous state then this process is known as boiling of substance.
When solid changes into liquid then there is decrease in force of attraction between the particles. On the other hand, when liquid changes into gaseous form then there are weak force of attraction between the molecules and they tend to move far apart from each other.
Thus, we can conclude that bonding forces determines the temperature at which a substance melts and boils.
