In what condition extraction of `Mg` is possible by `MgO` using carbon reduction method.

Explanation

To extract magnesium (Mg) from magnesium oxide (MgO) using the carbon reduction method, we need to consider the conditions under which this reaction can occur. Here’s a step-by-step solution:

### Step 1: Understanding the Reaction
The carbon reduction method involves the reaction of magnesium oxide with carbon. The general reaction can be represented as:
\[ \text{MgO} + \text{C} \rightarrow \text{Mg} + \text{CO} \]

### Step 2: High Temperature Requirement
According to the Ellingham diagram, the reduction of metal oxides by carbon typically requires very high temperatures. For magnesium oxide, this temperature is around 2000 Kelvin (or approximately 1727 degrees Celsius). Therefore, the first condition for the extraction of magnesium is:
