Order
Detailed explanations for each step

Answer 1

Order.

Explanation:

When we are proving a proposition, it's important to have order in our 2-column proof.

So, we must have a left colum for Statements and a right colum for Reasons, that's the order we need to have.

In the statements colum we write our deductions. In the reasons column, we write the justification or reason about our deduction.

Therefore, the right answer is the third choice: Order.
