Can y'all help me with this? First correct answer gets brainliest!

The figure below shows rectangle ABCD with diagonals segment AC and segment DB:

Image attached!

Jimmy wrote the following proof to show that the diagonals of rectangle ABCD are congruent:

Jimmy's proof:
Statement 1: Rectangle ABCD is given
Statement 2: segment AB ≅ segment DC because opposite sides of a rectangle are congruent
Statement 3: Angles ABC and DCB are both right angles by definition of a rectangle
Statement 4: Angles ABC and DCB are congruent because all right angles are congruent)
Statement 5:
Statement 6: Triangles ABC and DCB are congruent by SAS
Statement 7: segment AC ≅ segment DB by CPCTC

Which statement below completes Jimmy's proof?

segment AD ≅ segment AD (reflexive property of congruence)

Feedback for this selection: Segment AD is not a part of either of the triangles Jimmy would like to prove congruent; therefore, this choice is incorrect.

segment AD ≅ segment AD (transitive property of congruence)

segment BC ≅ segment BC (reflexive property of congruence)

segment BC ≅ segment BC (transitive property of congruence)
