It is a form when machining of brittle material like cast iron, brass etc. With slow cutting speed. Chips cut into small segment during cutting. This is formed during slow cutting speed with a small rack angle.

Cast iron is not a brittle material, it is a harder material.

Cast iron is a brittle and hard material. So very small parts or segmental form of chips are crated during machining of cast iron.

Segmental means discontinuous, breked chips are formed during machining, cast iron is brittle material so it formed segmental chips.

From Fe3C diagram we know that in all types of steels the carbon is up to 2% and from 2% to 6. 6% carbon content is found in cast iron. So if the carbon % is more then the brittleness of the substance will be more and the more brittle material will have more tendency to generate segmental chips during machining.

It is Due the presence of carbon.

Anyone give details of high carbon steel.

It can resist compressive loads, the chips are discontinuous or segmented because it is mixed graphite. So the chips are discontinuous.

Continuous chips form during machining ductile material. Cast iron contain large % of carbon than steels hence it is harder than steel.

B is correct in 90° Cases but when machining with less cutting speeds continuous chips can be formed.
