Answer: `INSERT INTO my_table VALUES ('a1', 6, 9.4)`

## Explanation **Option A** is correct because it follows the standard SQL syntax for inserting data into a table: ```sql INSERT INTO table_name VALUES (value1, value2, value3, ...) ``` **Option B** is incorrect because the syntax `INSERT VALUES ... INTO table_name` is not valid SQL syntax. The correct order is `INSERT INTO table_name VALUES (...)`. **Option C** is incorrect because `UPDATE` is used to modify existing records, not to insert new records. The UPDATE statement requires a SET clause and typically a WHERE clause, not a VALUES clause. **Option D** is incorrect for the same reason as option C - UPDATE is for modifying existing data, not inserting new records, and the syntax is completely invalid. ### Key Points: 1. **INSERT INTO** is used to add new rows to a table 2. **VALUES** clause contains the data to be inserted 3. **UPDATE** is used to modify existing records and requires different syntax 4. The order of keywords matters in SQL syntax For Delta tables specifically, the standard SQL INSERT syntax works perfectly, and Databricks SQL supports this syntax for appending data to Delta tables.
