Best answer
Right choice is (b) False

Easy explanation: When the molten metal is ladled into the shot chamber of the machine either manually by a hand ladle or by an auto ladle, which is a form of a robotic device. This process reduces the contact time between the molten metal and the shot chamber, so the high melting temperature materials can be cast easily.
