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 :

Options

A. `XltYltZ`
B. `YltXltZ`
C. `ZltYltX`
D. `XltZltY`

Explanation

To solve the problem, we need to identify the elements X, Y, and Z based on the nature of their oxides: basic, amphoteric, and acidic. The elements are from the 3rd period of the periodic table, which includes the following elements:

1. Sodium (Na) - Atomic number 11
2. Magnesium (Mg) - Atomic number 12
3. Aluminum (Al) - Atomic number 13
4. Silicon (Si) - Atomic number 14
5. Phosphorus (P) - Atomic number 15
6. Sulfur (S) - Atomic number 16
