Solution

The correct option is A Acidic
Non-metals on reaction with oxygen gas give rise to non-metallic oxides. These non-metallic oxides on reaction with $H_{2} O$ give acidic substance.

For example, sulphur is a non-metal. It forms $S O_{2}$ and $S O_{3}$ and forms $H_{2} S O_{3}$ and $H_{2} S O_{4}$ on reaction with water. On a pH scale, acids always have a value which is less than 7.

Thus, X is acidic in nature.
