Which one does a ER NOT have?
A
Smooth
B
Rough
C
Brittle
D
None of the above
Explanation: 

Detailed explanation-1: -Which of the following materials don’t give brittle fracture? Explanation: Aluminum shows a ductile fracture. White and grey cast iron and ceramics show brittle fracture.

Detailed explanation-2: -Brittle materials include glass, ceramic, graphite, and some alloys with extremely low plasticity, in which cracks can initiate without plastic deformation and can soon evolve into brittle breakage.

Detailed explanation-3: -Ductility in Aluminum and Other Metals On the other hand, silicon, boron, and germanium are some of the most brittle metals. Impure or hardened alloys such as tungsten carbides and cast iron are also quite brittle.

Detailed explanation-4: -5.2. Brittle fracture means fracture of material without plastic deformation or with very small plastic deformation before fracture. Rock, concrete, glass, and cast iron all have such property, so they are called brittle materials.
