An oxide $$X$$ in its normal form is almost non-reactive due to very high $$X - O$$ bond enthalpy. It resists the attack by halogens, hydrogen and most of acids and metals even at elevated temperatures. It is only attacked by $$HF$$  and $$NaOH.$$ The oxide $$X$$ is
A.
$$Si{O_2}$$
B.
$$C{O_2}$$
C.
$$Sn{O_2}$$
D.
$$Pb{O_2}$$
Answer :
$$Si{O_2}$$
Solution :
$$Si{O_2}$$ is attacked by $$HF$$ and $$NaOH$$ but not by chemicals under normal conditions.
