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
[A].
the material A is more ductile than material B
[B].
the material B is more ductile than material A
[C].
the ductility of material A and B is equal
[D].
the material A is brittle and material B is ductile
