Correct Option: C

AI Explanation

To answer this question, we need to understand the different options and their meanings:

Option A) %ID - This option is incorrect because %ID is not a valid option for completing a variable declaration for a column value.

Option B) %ROWTYPE - This option is incorrect because %ROWTYPE is used to declare a record variable that can hold an entire row of a table or view. It is not used to declare a specific column value.

Option C) %TYPE - This option is correct because %TYPE is used to declare a variable with the same datatype as a specified column. In this case, it would declare the variable "l_foo_column_id" with the same datatype as the column "SOME_COLUMN" in the table "SOME_TABLE".

Option D) %COLUMNTYPE - This option is incorrect because %COLUMNTYPE is not a valid option for completing a variable declaration for a column value.

Therefore, the correct answer is C) %TYPE. This option is correct because it allows us to declare the variable with the same datatype as the specified column.
