- B \(\mathrm{BCC}\)
- C Hexagonal
- D Simple cubic
Answer & Solution
Correct Answer
(D) Simple cubic
Step-by-step Solution
Detailed explanation
\(
\mathrm{FCC} \rightarrow 74 \% \quad \mathrm{BCC} \rightarrow 68 \%
\)
Hexagonal \(\rightarrow 74 \% \quad\) Simple cubic \(\rightarrow 52.36 \%\)
\mathrm{FCC} \rightarrow 74 \% \quad \mathrm{BCC} \rightarrow 68 \%
\)
