Step by step solution

Understand the different file access flags

Familiarize yourself with the different file access flags (modes) that can be used for opening a file. Some of these commonly used modes are: 1. 'r' - Read mode 2. 'w' - Write mode 3. 'a' - Append mode 4. 'x' - Exclusive creation mode 5. 'b' - Binary mode 6. 't' - Text mode

Identify the required file access flag

Review the descriptions of these modes and identify which one is suitable for opening a file to write data at the end of its existing content without overwriting it. In this case, the 'a' flag (Append mode) is the correct choice. Using the 'a' flag, the file is opened for appending new data at the end of the existing content while keeping the original content intact.
