The answer is Daniel is correct, but Kelly is not.

Step-by-step explanation:

(D) Daniel is correct, but Kelly is not.

Step-by-step explanation:

It is given that Line segment NT intersects line segment MR forming four angles. Angles 1 and 3 are vertical angles. Angles 2 and 4 are vertical angles.

Kelly's Proof:∠2 = ∠4 (Vertical angles are congruent)

∠1 = ∠3(Vertical angles are congruent)

Using Vertical Angle Theorem  the vertical angles are equal.

since, we cannot use the direct information given in the question in order to prove the same.

Thus, the justification given by Kelly is incorrect.

Now, Daniel's proof:

∠1 + ∠2 = 180°(Definition of Supplementary Angles)

and ∠1 + ∠4 = 180° (Definition of Supplementary Angles)

⇒∠1 + ∠2 = ∠1 + ∠4(Transitive Property of Equality)

Hence,  ∠2 = ∠4(Subtraction Property of Equality)

Thus, the justification of Daniel is correct.

Hence, option (D) is correct.
