The text in the image is as follows:

---

**File.txt contains two lines:**

```
This
And this is line2
```

**What is the output of the following code snippet?**

```cpp
int main()
{
    ifstream read_file;
    read_file.open("File.txt");

    string line1, line2;
    read_file >> line1;
    getline(read_file, line2);

    cout << line1 << endl;
    cout << line2 << endl;
    return 0;
}
```

**Options:**

1. ( ) This
       And this is line2

2. ( ) This And this is line2

3. ( ) This

4. ( ) This is line2

---

**Explanation:**

The code snippet reads from "File.txt" using two different methods: the extraction operator (`>>`) and `getline()`. The first method reads a single word ("This") into `line1`, and `getline()` reads the rest of the first line including whitespace (which is none) and the second line into `line2`. Thus, the output will be:

```
This
 And this is line2
```

The first option is the correct choice. Note the extra space at the beginning of the second line output due to the leading space from the file.
