Question

Match List-I with List-II

Choose the correct answer from the options given below:

• (A) (I), (B) (II), (C) (III), (D) (IV)
• (A) (III), (B) (I), (C) (IV), (D) (II)
• (A) (I), (B) (II), (C) (IV), (D) (III)
• (A) (III), (B) (IV), (C) (I), (D) (II)

Hint:

The carbon content in materials like steel and cast iron classifies them into hypo and hyper categories, which affects their properties and applications.

Answer 1

The Correct Option is C

Step 1: Understand the carbon content for various steels and cast iron. - Hypo-eutectoid steel has less than 0.8\% carbon (option I),
- Hyper-eutectoid steel has more than 0.8\% carbon but less than 2\% (option II),
- Hypo-eutectic cast iron has less than 2.0\% carbon (option III),
- Hyper-eutectic cast iron has more than 2.0\% carbon (option IV).
Step 2: Conclusion
The correct matching is:
- (A) Hypo-eutectoid steel → (I),
- (B) Hyper-eutectoid steel → (II),
- (C) Hypo-eutectic Cast Iron → (IV),
- (D) Hyper-eutectic Cast Iron → (III).
Final Answer: \[ \boxed{(A) (I), (B) (II), (C) (IV), (D) (III)} \]
