Incorrect Statement: Tar gets crystallized.

Explanation:
Tar:
Tar is a black, viscous liquid derived from a variety of organic materials, such as wood, coal, or petroleum. It is commonly used in road construction as a binding agent for asphalt pavement. Tar has a higher susceptibility to temperature changes compared to bitumen.

Bitumen:
Bitumen, also known as asphalt or asphalt cement, is a sticky, black, and highly viscous liquid or semi-solid form of petroleum. It is a natural binder used in the construction of roads, pavements, and waterproofing applications. Bitumen is less temperature susceptible compared to tar.

Now, let us analyze each statement:

Statement A: Tar is more temperature susceptible than bitumen.
Explanation:
This statement is correct. Tar is more temperature susceptible than bitumen. It becomes soft and viscous at higher temperatures and hardens and becomes brittle at lower temperatures. Temperature changes can significantly affect the properties of tar.

Statement B: Bitumen is not susceptible to dissolving action of petroleum.
Explanation:
This statement is correct. Bitumen is not susceptible to the dissolving action of petroleum. Bitumen is derived from petroleum and is insoluble in petroleum solvents. It is a highly stable material and does not dissolve or get affected by petroleum.

Statement C: Tar takes more time to set.
Explanation:
This statement is correct. Tar takes more time to set compared to bitumen. Tar requires a longer curing time to harden and achieve its desired properties. This is one of the reasons why bitumen is more commonly used in road construction, as it sets relatively faster.

Statement D: Tar gets crystallized.
Explanation:
This statement is incorrect. Tar does not get crystallized. Crystallization refers to the formation of a crystalline structure, which is not observed in tar. Tar, being a highly viscous liquid, does not have a crystalline form.

In summary, all the statements are correct except for statement D, which states that tar gets crystallized. Tar does not undergo crystallization.
