The correct option is B.
Alloy steel chains are usually opted for because they are strong, durable, resistant to abrasion and they have the ability to conform to the shape of the loads that they are carrying. In addition to all these properties, they also have the capacity to carry hot materials. These chains are typically made from various grades of alloys, therefore, manufacturers normally marked them in accordance with American Society for Testing and Maintenance guidelines. The chains are usually marked to show the following: size, grade, length and load capacity. The chain are often also marked with serial numbers and the manufacturers' names and brands.
Thus, all the facts mentioned about alloy steel chains in the options given above are correct. 

Answer: Option (B) is the correct answer.

Explanation:

A metal that tends to combine with two or more metal elements in order to gain strength or durability etc is known as an alloy.

For example, an alloy of steel contains elements like manganese, silicon, nickel, titanium, copper etc.

Some properties of alloys of steel are as follows.

  • They are able to adapt to the shape of the load applied.
  • They are the best choice for hoisting hot material.
  • Usually they are marked with a grade or manufacture’s mark.

Hence, we can conclude that all the given options are true about alloy steel chains.
