• C

• D

Explanation

In Snowflake's tag-based masking, a single tag can have at most one masking policy assigned per data type. For example, a tag named 'PII' can have one masking policy for STRING data and one for NUMBER data, but it cannot have two policies for the same data type. This constraint ensures deterministic behavior - when a tag is applied to a column, Snowflake can unambiguously select the correct policy based on the column's data type. A tag cannot be dropped while a masking policy is assigned to it, making option A incorrect.
