_ Steels with high carbon equivalent have poor weldability, because in these steels during welding$?

• A. Carbon and other alloying elements get oxidised from the weld pool
• B. Excessive ferrite forms in the heat affected zone leading to poor toughness of the weld
• C. Martensite forms in the heat affected zone leading to poor toughness/ductility of the weld
• D. Segregation of carbon and other element occurs in the weld pool leading to poor properties of the weld
