Concept:
Yield of dairy products depends on fat and total solids content of milk.
Step 1: Khoa from cow milk.
• Cow milk has lower fat compared to buffalo milk
• Typical yield is around 17–19%
Step 2: Chhana from buffalo milk.
• Buffalo milk is rich in fat and casein
• Produces higher yield of chhana
• Approximately 22–24%
Step 3: Surati paneer from cow milk.
• Paneer yield varies but Surati paneer has higher moisture retention
• Yield around 28–29%
Step 4: Chhana from cow milk.
• Lower yield compared to buffalo milk
• Around 16–18%
Step 5: Matching.
\[
A \rightarrow II,\quad B \rightarrow I,\quad C \rightarrow IV,\quad D \rightarrow III
\]
Conclusion: Option (2) correct.
