`(X), (Y), (Z)` are elements in third short period. Oxide of `(X)` is ionic, `(Y)` is amphoteric and `(Z)` is a giant molecule. `(X), (Y)` and `(Z)` will have atomic number in the order :

(a),(b) and (c) are elements in the second short period. Oxide of (a) is ionic, that of (b) is amphoteric and of (c) of gaint molecule. (a),(b) and (c) have atomic number in the order-

(a),(b) and (c) are elements in the second short period. Oxide of (a) is ionic, that of (b) is amphoteric and of (c) of gaint molecule. (a),(b) and (c) have atomic number in the order-

Three elements, X and Y and Z are present in the third short period and their oxides are ionic, amphoteic and giant molecule respectively. The correct order of atomic number of X, Y and Z is-

Three elements of 3^(rd) period x,y,z such that the oxide of X is acidic, y is amphoteric and z id basic, the order of atomic no of three elements isL

Three elements of 3^(rd) period x,y,z such that the oxide of X is acidic, y is amphoteric and z id basic, the order of atomic no of three elements isL

Three elements X, Y and Z are in the 3^(rd) periodic table. The oxides of X, Y and Z, respectively, are basic, amphoteric and acidic, The correct order of the atomic numbers of X, Y and Z is :

Three elements X, Y and Z are in the 3^(rd) periodic table. The oxides of X, Y and Z, respectively, are basic, amphoteric and acidic, The correct order of the atomic numbers of X, Y and Z is :
