If percentage reduction in area of a certain specimen made of material 'A' under tensile test is 60% and the percentage reduction in area of a specimen with same dimensions made of material 'B' is 40%, then
The material A is more ductile than material B
The material B is more ductile than material A
The ductility of material A and B is equal
The material A is brittle and material B is ductile
