- 2, 4
- 1, 4
- 2, 1
- 1, 2
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Unit cell atom counts.
Step 2: Analysis
Simple cubic unit cell contains 1 atom (corners). FCC unit cell contains 4 atoms (8 corners + 6 faces).
Step 3: Conclusion
The counts are 1 for simple cubic and 4 for FCC.
Final Answer: (B)
