\(SnO_2 \;and \;SiO\)
Amphoteric oxides exhibit dual reactivity, behaving as either acidic or basic oxides contingent on reaction conditions. These oxides can react with both acids and bases, yielding distinct products. Of the provided choices, \(SnO_2\) and \(PbO_2\) are recognized as amphoteric. Specifically, tin dioxide (\(SnO_2\)) and lead dioxide (\(PbO_2\)) both demonstrate amphoteric characteristics.
The correct option is (C): \(SnO_2 \;and \;PbO_2\)
