Dude hypo eutectic cast irons have 2-4.3% carbon. 0.77 to 2.1%C Hypereutectoid steel.

0 to 0.8% = Hypo and 0.8 to above is Hyper.

0-0.8%c hypo eutectic.
0.8-2.0% hyper eutectic.
2.1-4.3%c hypo eutectic.
4.3-6.67%c hyper eutectic.
0.8-2.0% hyper eutectic.
2.1-4.3%c hypo eutectic.
4.3-6.67%c hyper eutectic.

0.8 eutectic.
>o.8 hyper.
<o.8 hypo.
>o.8 hyper.
<o.8 hypo.

Eutectic irons contains 0.8% of corbon. And the given range is higher than that. Hence answer is C. HYPEREUTECTIC CAST IRON.

Eutectic CI having %c = 4.3.
Hypo eutectic CI %c < 4.3.
Hypereutectic CI %c > 4.3.
Eutectic steel %c = 0.8.
Hypo eutectic steel %c < 0.8.
Hypereutectic steel %c > 0.8.
Hypo eutectic CI %c < 4.3.
Hypereutectic CI %c > 4.3.
Eutectic steel %c = 0.8.
Hypo eutectic steel %c < 0.8.
Hypereutectic steel %c > 0.8.

0- 0.8% c - Hypo eutectoid
0.8- 2.0%c- Hyper eutectoid
2.1- 4.3%c- Hypo eutectic.
4.3- 6.67%c- Hyper eutectic.
0.8- 2.0%c- Hyper eutectoid
2.1- 4.3%c- Hypo eutectic.
4.3- 6.67%c- Hyper eutectic.
