A. Passing –O when running python
B. Assertions are disabled by default
C. Both A and B are wrong
D. Assertions cannot be disabled in python

Solution

A. Passing –O when running python

Explanation

Assertions in Python can be disabled by running the Python interpreter in optimized mode. This is done by using the -O (capital letter "O", not zero) flag when starting the interpreter. When Python is run with this flag, all assert statements in the code are ignored.
