Nope, none of this. React doesn't use real DOM elements when rendering, they're just lightweight objects that represent components. Those descriptors are reconciled into real DOM elements by React under the hood when mounting/updating components. This is a REALLY important concept to understand when using React.

In this case, instead of creating an actual `option` element, you'd use the `React.DOM.option` function. But, luckily, we're using JSX, so we can write it similarly to HTML (and it gets transformed into the function). This is what this function should actually look like:

```javascript
// By convention, I name all functions that render components `render*`
renderOption: function(country, index, countries) {
  return <option value={country.id}>{country.name}</option>;
},
```
