1. Asphalt is manufactured by fractional distillation of crude petroleum. 
2. Tar is manufactured by fractional distillation of organic materials.
A.
Both statements are correct
B.
Statement 1 is correct but Statement 2 is incorrect 
C.
Both statements are incorrect
D.
Statement 1 is incorrect but Statement 2 is correct
Answer ( Option B)

Statement 1 is correct but Statement 2 is incorrect 

Solution

Asphalt: 
• It is indeed manufactured by fractional distillation of crude petroleum. During the refining process of crude oil, asphalt is obtained as a residue after the lighter fractions, such as gasoline and diesel, have been separated through fractional distillation. 
Tar: 
• It is not typically manufactured by fractional distillation of organic materials. 
• Tar is a viscous, dark liquid that is derived from a variety of organic materials, such as coal, wood, or peat, through a process called destructive distillation or pyrolysis. 
• It involves heating the organic materials in the absence of air to produce tar as a byproduct. 
Hence, Statement 1 is correct but Statement 2 is incorrect.
