●Hypo-eutectic
CI : Carbon content below 4.3% of the alloy is called hypo-eutectic CI.
●Hyper-eutectoid
steel : Hyper-eutectoid steels contain 0.8 - 2.0% carbon.
●Hypo-eutectoid
steel : Hypo-eutectoid steels contain less than 0.8%
of carbon content.
●Hyper-eutectic
CI : Carbon content above 4.3% of the alloy is called hyper-eutectic CI.
Hence,
the correct option is (D).
