Question

Assertion (A): For a binary file opened using 'rb' mode,
the pickle.dump() method will display an error.
Reason (R): The pickle.dump() method is used to read from a binary file.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation for Assertion (A).
• B. Both Assertion (A) and Reason (R) are true and Reason (R) is not the correct explanation for Assertion (A).
• C. Assertion (A) is true but, Reason (R) is false.
• D. Assertion (A) is false but, Reason (R) is true.

Hint:

Use pickle.dump() to write,
and pickle.load() to read.
Always match the file mode accordingly.

Answer 1

The Correct Option is C

The pickle.dump() method is used to write data to a binary file.
It serializes a Python object and writes it to an open binary file in write mode,
commonly opened with 'wb'.
If the file is opened in read-only binary mode ('rb'),
trying to write using pickle.dump() will cause an error,
because the file does not allow writing.
Therefore, Assertion (A) is true.
However, Reason (R) is false because pickle.dump() does not read;
instead, pickle.load() is used to read from a binary file.
Hence, the correct choice is (C).
