1. dir(math)[01]
dir(math) returns a list of strings (names of attributes in the math module).
01 is interpreted as 1 (Python allows leading zeros for integers in older versions but it's discouraged).
So dir(math)[1] is a string, like 'acos'.
Therefore, type(...) is str → True ✅
2. sys.path[-1]
sys.path is a list of strings representing module search paths.
sys.path[-1] is the last entry (usually a string or empty string).
So type(...) is str → True ✅
3. print(b1 and b2)
Both are True, so b1 and b2 → True
This will output nothing since it results in a Syntax error due to the 01:
SyntaxError: leading zeros in decimal integer literals are not permitted; use an 0o prefix for octal integers
It will be B True if the 01 is corrected to just 0 or just 1
