Answer: SHOW NETWORK POLICIES

The correct answer is D because the SHOW NETWORK POLICIES command is specifically designed to list all network policies available in a Snowflake account. This is confirmed by the Snowflake documentation link provided in the community discussion, which shows this is the proper SQL command for this purpose. Option A (DESCRIBE SESSION POLICY) is incorrect as it describes a specific session policy rather than listing network policies. Option B (DESCRIBE NETWORK POLICY) is incorrect as it describes a specific network policy rather than listing all available ones. Option C (SHOW SESSION POLICIES) is incorrect as it deals with session policies, not network policies. The community discussion shows 100% consensus on answer D with supporting documentation evidence.
