The characteristics of elements X, Y and Z with atomic numbers, respectively, 33, 53 and 83 are :
X and Y are metalloids and Z is a metal.
X and Z are non-metals and Y is a metalloid.
X is a metalloid, Y is a non-metal and Z is a metal.
X, Y and Z are metals.
Explanation
X(Z = 33) = As (metalloid)
Y(Z = 53) = I (non-metal)
Z(Z = 83) = Bi (metal)
Y(Z = 53) = I (non-metal)
Z(Z = 83) = Bi (metal)
