Consider the multiplicative group zs* of non-zero integers modulo 5 and additive group z4. let d: ( z4, +)-(zs*, x) be a map defined as d(m) = 3" o d is not a h

Consider the multiplicative group Zs* of non-zero integers modulo 5 and additive group Z4. Let d: ( Z4, +)-(Zs*, x) be a map defined as d(m) = 3" O d is not a homomorphism co is a homomorphism but not one- O one mapp o is a homomorphism but not onto O map is a homomorphism and bijective O map
