Answer: POLICY_REFERENCES

The POLICY_REFERENCES view in the ACCOUNT_USAGE schema is specifically designed to track policy assignments to objects in Snowflake, including masking policies. This is confirmed by the community discussion where both comments with upvotes reference the official Snowflake documentation and state that POLICY_REFERENCES shows which masking policies are assigned to objects. The other options are incorrect: ACCESS_HISTORY tracks query access patterns, OBJECT_DEPENDENCIES shows object relationships, and TAG_REFERENCES tracks tag assignments, none of which directly identify masking policy assignments.
