The answer is B
Tin is not as reactive as the alkali earth metals or even earth metals
This is simply due to its lower electropositivity
Hence , tin is unaffected at room temperature
Tin is unaffected by air at ordinary temperature due to its **weak electropositive character** (Option B). This property makes tin quite resistant to the impact of air or water, as a thin oxide film forms on the surface of the metal. Tin starts to oxidize in air at a temperature of over 150 °C. This resistance to oxidation and corrosion is one of the reasons why tin is used to coat other metals to prevent corrosion.
Thank you all for your contributions. Kindly note that the necessary correction has been effected.
In your explanation, it was stated that the boilingpoint of tin is above 230c, so A is never the ans.
Tin has a relatively low position in the ECS, hence it is not easily oxidised by atmospheric oxygen.
