Answer 1

C. By using a prompt function in JavaScript

In JavaScript, you can use the prompt function to display a pop-up box and ask the user to enter their name. Here is an example code snippet:

```javascript
var userName = prompt("Please enter your name:");
console.log("Hello, " + userName + "!");
```

This code will display a pop-up box with a text input field where the user can enter their name. The name entered by the user will be stored in the `userName` variable and then displayed in the console.
