A.
Ferrous alloys with low melting temperature are casted
B.
Ferrous alloys with high melting temperature are casted
C.
Nonferrous alloys with low melting temperature are casted
Answer
D.
Nonferrous alloys with high melting temperature are casted

Answer: Option C

Solution

Answer: Option C
Solution:
