Which of the following is correctly matched?

  1. A
    Basic oxides ⇒In2O3, K2O,SnO2\Rightarrow \mathrm{In}_2 \mathrm{O}_3, \mathrm{~K}_2 \mathrm{O}, \mathrm{SnO}_2⇒In2​O3​, K2​O,SnO2​
  2. B
    Neutral oxides ⇒CO,NO2, N2O\Rightarrow \mathrm{CO}, \mathrm{NO}_2, \mathrm{~N}_2 \mathrm{O}⇒CO,NO2​, N2​O
  3. C
    Acidic oxides ⇒Mn2O7,SO2,TeO3\Rightarrow \mathrm{Mn}_2 \mathrm{O}_7, \mathrm{SO}_2, \mathrm{TeO}_3⇒Mn2​O7​,SO2​,TeO3​
  4. D
    Amphoteric oxides ⇒BeO,Ga2O3,GeO\Rightarrow \mathrm{BeO}, \mathrm{Ga}_2 \mathrm{O}_3, \mathrm{GeO}⇒BeO,Ga2​O3​,GeO
