A. Enforcing antitrust laws - This is a government activity related to promoting competition and preventing monopolies, so it aligns with the statement.
B. Enforcing building codes - This is also primarily a government function to ensure safety standards, which fits the context.
C. Creating pure food and drug laws - The creation of laws is a government role, but it is less about activities typically conducted privately.
