Final Answer :
A
Explanation :
The brittleness in hot steel is known as hot shortness and it is caused by the presence of excess sulfur in the steel. Sulfur combines with iron to form iron sulfide, which can form a liquid at the high temperatures of hot rolling and cause the steel to crack and break.
