Question
The diagram shows two parallel lines, \( m \) and \( n \), intersected by a transversal, \( k \). Angles \( A \), \( B \), and \( C \) are marked in the diagram.

A student has written a proof to demonstrate that the corresponding angles, \( A \) and \( B \), are congruent. The proof is outlined in the following table:

| Statements                       | Reasons                         |
|----------------------------------|---------------------------------|
| 1. \( m \parallel n \)           | Given                           |
| 2. \( \angle A \cong \angle C \) | Vertical angles are congruent   |
| 3. \( \angle B \cong \angle C \) | Vertical angles are congruent   |
| 4. \( \angle A \cong \angle B \) | Transitive Property             |

The task asks to evaluate the validity of Reasons 2 and 3:

A. Both Reason 2 and Reason 3 are correct as shown in the table.

B. Reason 2 is correct, but Reason 3 should be "Alternate interior angles are congruent".

C. Reason 2 should be "Alternate interior angles are congruent," but Reason 3 is correct.

D. Both Reason 2 and Reason 3 should be "Alternate interior angles are congruent".
