Assertion (A): The readline() method reads one complete line from a text file.

Reasoning (R): The readline() function can also be used to read a specified number (n) of bytes of data from a file but maximum up to the newline character (\n).

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Both A and R are true and R is the correct explanation of A.
