A white solid oxide, YYY, of a Period 3 element is insolubly suspended in water. When Y Y\,Y is heated with concentrated aqueous sodium hydroxide, it dissolves to form a colourless solution. However, Y Y\,Y shows no reaction when heated with concentrated hydrochloric acid.

Which of the following is the correct formula and structure of oxide YYY?

Al2O3\text{Al}_2\text{O}_3Al2​O3​ with a giant ionic structure containing covalent character

SiO2\text{SiO}_2SiO2​ with a giant covalent structure

SiO2\text{SiO}_2SiO2​ with a simple molecular structure

P4O10\text{P}_4\text{O}_{10}P4​O10​ with a simple molecular structure
