The correct answer is (a) True

For explanation I would say: The friction concept is very useful in explaining the increased tendency of breakout with the increase in casting speed. Analysis of friction at the interface of mould and casting is done to specify the speed of the casting process or it can also be adjusted by maintaining the amount of lubrication at the gap.
