Explanation

The correct answer is D. COMMENT "Contains PII".

In Databricks SQL, you can add comments to tables using the COMMENT clause when creating a table. The syntax is:

COMMENT 'comment text'

COMMENT 'comment text'

For this specific scenario, to indicate that the table contains personally identifiable information (PII), you would add:

COMMENT 'Contains PII'

COMMENT 'Contains PII'

This would be added to the CREATE TABLE statement as follows:

CREATE TABLE customersInFrance
COMMENT 'Contains PII'
AS
SELECT id,
       firstName,
       lastName,
FROM customerLocations
WHERE country = 'FRANCE';

CREATE TABLE customersInFrance
COMMENT 'Contains PII'
AS
SELECT id,
       firstName,
       lastName,
FROM customerLocations
WHERE country = 'FRANCE';

Let's analyze why the other options are incorrect:

A. There is no way to indicate whether a table contains PII. - This is incorrect because Databricks provides multiple ways to document table properties, including comments.

B. "COMMENT PII" - This is incorrect syntax. The COMMENT clause requires the comment text to be in quotes.

C. TBLPROPERTIES PII - While TBLPROPERTIES is a valid clause in Databricks, the syntax would require a key-value pair like TBLPROPERTIES ('pii' = 'true'). The option shown doesn't follow proper syntax.

E. PII - This is not a valid SQL clause for table creation.

Table comments are a standard way to document metadata about tables in Databricks and other SQL databases, making them an appropriate choice for indicating PII content according to organizational policies.
