The following is an incorrect flowchart proving that point L, lying on line LM which is a perpendicular bisector of segment JK, is equidistant from points J and K:

Segment JK intersects line LM at point N (PICTURE BELOW)

Line LM is a perpendicular bisector of segment JK, Given. Two arrows are drawn from this statement to the following two statements ({PICTURE BELOW})

What is the error in this flowchart?

Select one:
a. JL and KL are equal in length, according to the definition of a midpoint.
b. An arrow is missing between ∠LNK = 90° and ∠LNJ = 90° and ∠LNK ≅ ∠LNJ.
c. An arrow is missing between the given statement and ∠LNK ≅ ∠LNJ.
d. Triangles JNL and KNL are congruent by the Angle-Angle Side (AAS) Postulate.
