Hint: Carbon is less reactive metal, if we see the reactivity series sodium and magnesium are highly reactive metals, and carbon is a strong oxidizing agent. Therefore, it cannot reduce the strong metal oxides.
Complete step by step answer:
- Firstly, we will see the reactivity series i.e. K > Na > Ca > Mg > Al > C > Zn > Fe.
- Now as mentioned in the series we can say that sodium (Na), and magnesium (Mg) are placed at the upper position, and carbon is at the lower position.
- Thus, it means Na, and Mg are highly reactive metals. So, we can also say that the oxides of sodium, and magnesium are very strong.
- Carbon is a non-metal and is not a strong reducing agent. It can reduce the zinc as zinc is less reactive than carbon.
- Now, the reactivity series clearly explains that carbon cannot reduce the sodium, and magnesium due to their highly reactive nature.
- Thus, Na, and Mg represents higher affinity towards the oxygen because oxygen is highly reactive and it can easily reduce these metals.
- So, the correct option is A i.e. assertion and reason both are correct and reason is the correct explanation for assertion.
Note: Don’t get confused, just write down the correct reactivity series and by the mention of reactivity series we can see that the carbon is less reactive than the mentioned elements.
