If 'rt' is right, can't 'rb' be right as well?

The question asks for text mode, rb will open the file in binary mode.

The documentation doesn't mention 'rt' at all, only 'r' and 'rb': https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files

Did some research, 't', text, is the default, so you don't HAVE to have it. But, on systems that differentiate, or where you want to be precise (just in case), it's an optional add. Regardless, seems to be the only possible right answer.

Ref. in the QotD explanation refers to the documentation for Built-in Functions and the open() function not to Input and Output. In the documentation for Built-in Functions, the use of mode characters in the open() function is well explained.
