B)FCC
C)HCP

Question

Quizplus · Accepted Answer

HCP (Hexagonal Close-Packed) structures have fewer slip systems compared to FCC (Face-Centered Cubic) and BCC (Body-Centered Cubic) structures. This limited number of slip systems makes HCP metals generally more difficult to deform at room temperature.
