C Correct answer
Explanation

Catch_#22 is valid because it starts with a letter and contains only allowed characters (letters, numbers, underscore, and #). 1966_Invoices is invalid (starts with number), #Invoices is invalid (starts with special character), and Column may be a reserved word depending on the database system.
