The line of code

```javascript
document.getElementById("firstGreeting").innerHTML = "Welcome!";
```

will **put the word “Welcome!” into the element whose ID is firstGreeting**.

This means it targets the HTML element with the ID `firstGreeting` and sets its inner HTML content to "Welcome!". The other options provided do not accurately describe what the code does.
