A

``` f = open('pattern.txt', 'r') letters = 'abcdefghijklmnopqrstuvwxyz' n = len(letters) // 2 for i in range(n): line = letters[i] + letters[-1 - i] if i != n - 1: line = line + '\n' f.write(line) f.close() ```

B

``` f = open('pattern.txt', 'w') letters = 'abcdefghijklmnopqrstuvwxyz' n = len(letters) // 2 for i in range(n): line = letters[i] + letters[-1 - i] f.write(line) f.close() ```

C

``` f = open('pattern.txt', 'w') letters = 'abcdefghijklmnopqrstuvwxyz' n = len(letters) // 2 for i in range(n): line = letters[i] + letters[-1 - i] if i != n - 1: line = line + '\n' f.write(line) f.close() ```

D

``` f = open('pattern.txt', 'w') letters = 'abcdefghijklmnopqrstuvwxyz' n = len(letters) for i in range(n): line = letters[i] + letters[-1 - i] if i != n - 1: line = line + '\n' f.write(line) f.close() ```
