Which of the following File open modes is used for opens the file in r...

The correct answer is option C.
Concept:
To open a file in Python:
we use the open() function. The syntax of open() is as follows:
file_object= open(file_name, access_mode)
The access_mode is an optional argument that represents the mode in which the file has to be accessed by the program. It is also referred to as processing mode.
Different File open modes:

<wb+> or <+wb> Opens the file in read, write, and binary mode. If the file already exists, the contents will be overwritten. If the file doesn’t exist, then a new file will be created.
<r> Opens the file in read-only mode.
<rb> Opens the file in binary and read-only mode.
<w> Opens the file in write mode. If the file already exists, all the contents will be overwritten. If the file doesn’t exist, then a new file will be created.
<a> Opens the file in append mode. If the file doesn’t exist, then a new file will be created.

Hence the correct answer is<wb+> or <+wb>.
