Determine whether the parallelogram is a rhombus, rectangle, square, or none. Explain. Q(1, 3), R(3, 4), S(5, 3), T(3, 2)

Select one:
A. QRST is a rhombus that is not a square because its diagonals are perpendicular but not congruent.
B. QRST is a rectangle that is not a square because its diagonals are congruent but not perpendicular.
C. QRST is a square because its diagonals are both perpendicular and congruent.
D. QRST is none of these because its diagonals are neither congruent nor perpendicular.
