Explanation

In this scenario, you're working with the pickle module to serialize data into a file. Let's look at statement 4 in the context of the code:

f = open("stud.dat", "____________")  # statement 2
__________ .dump(rec, f)  # statement 3
_______.close()  # statement 4

Explanation of the code:

Statement 1 imports the necessary module, likely pickle because .dump() is used.
Statement 2 opens the file stud.dat in write-binary mode (wb), allowing us to write binary data to it.
Statement 3 uses pickle.dump() to serialize the rec list and save it to the file f.
Statement 4 should close the file f after writing. To do this, you call .close() on the file object f.
