In a glassy solid (i.e., amorphous solid) the various bonds between the atoms or ions or molecules of a solid are not equally strong. Different bonds are broken at different temperatures. Hence there is no sharp melting point for a glassy solid.

Assertion: Glassy solids have sharp melting point.
Reason: The bonds between the atoms of glassy solids get broken at the same temperature.
Explanation:
A glassy solid is a type of amorphous solid that lacks long-range order in its atomic structure. Unlike crystalline solids, which have a well-defined repeating pattern, glassy solids have a disordered arrangement of atoms.
The assertion states that glassy solids have a sharp melting point. This means that glassy solids transition from a solid to a liquid state at a specific temperature.
The reason given for this assertion is that the bonds between the atoms of glassy solids get broken at the same temperature. In other words, when the temperature reaches a certain point, the bonds holding the atoms together in the glassy solid structure weaken and break, allowing the atoms to move more freely and transition into a liquid state.
However, this reason is not entirely correct. In reality, glassy solids do not have a well-defined melting point like crystalline solids. Instead, they undergo a process called glass transition, where they gradually soften and become less rigid as the temperature increases. This transition is not characterized by a sharp change in physical properties, such as melting, but rather by a gradual change in viscosity and molecular mobility.
Glassy solids have a range of temperatures over which they soften and become more fluid, rather than a specific melting point. This is due to their disordered atomic structure, which lacks the regularity and symmetry found in crystalline solids.
Therefore, the correct answer is option D: If the assertion and reason both are false. The assertion that glassy solids have a sharp melting point is false, and the reason provided to support it is also incorrect.
Reason: The bonds between the atoms of glassy solids get broken at the same temperature.
