A)
B)
C)
D)
Explanation:
Let's break down the code for statement 2.
Context:
The code involves writing data (a list of records) into a file, and since we're using serialization (as inferred from the usage of .dump()), the file should be opened in binary write mode.
Explanation:
f = open("stud.dat", "____________"):

Answer:
(B) wb
