Consider the following code segment:
primes = {2, 3, 5, 7}
odds = {1, 3, 5, 7}
x = primes.issubset(odds)
What value will be stored in x after it has executed?

Question

The question presents a Python code snippet and asks what value x will hold after execution. 
First, restating the setup: primes is the set {2, 3, 5, 7}, odds is the set {1, 3, 5, 7}, and x is assigned the result of primes.issubset(odds). 
Now, evaluate each provided option in turn.

Option 0: "0". In Python, booleans are True or False, not 0 or 1. If you expected a numeric value, note that set.issubset returns a boolean, not an integer. Therefore, this option does not reflect the actual return type or value of the expression.

Option 1: "1". Similar to the previous, 1 is an integer, not a boolean. The issubset method yields a boolean True or False, so 1 would be incorrect as a representation of the boolean result.

Option 2: "False". This aligns with the actual behavior: primes.issubset(odds) checks whether every element of primes is also in odds. Since 2 is in primes but not in odds, the subset relation does not hold. Therefore the boolean result is False, which corresponds to this option.

Option 3: "True". This would imply that primes is a subset of odds, which would require all elements of primes to appear in odds. But 2 is missing from odds, so the statement is false, making this option incorrect.

Putting it together, the key idea is understanding what subset means in Python: issubset returns True only if every element of the first set is contained in the second set. Since 2 is missing from odds, the check fails, yielding False rather than True. The numeric-looking options (0 or 1) do not represent the boolean result, while the only logically correct boolean value is False. Therefore, Option 2 is the correct choice, and the others are incorrect for the reasons described.
