\(68.00\%\)
\(47.6\%\)
\(26.00\%\)
\(32.00\%\)

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
Hexagonal close packing (hcp) has the same packing efficiency as ccp, 74 percent.
Step 2: Calculation
Void volume \(=100-74=26\%\).
Step 3: Compare the options
26.00% is option (C).
Final Answer:
The void volume in hcp is 26 percent. \[ \boxed{\text{(C) }26.00\%} \]
