Which of the Following Statements Accurately Describes PNF Reversal of Antagonists

Which of the following statements accurately describes PNF reversal of antagonists techniques?

B) Stabilizing reversals are isotonic contractions of the antagonists followed by an isotonic contraction of the agonist.
C) Rhythmic stabilization increases stability through contractions of only the antagonistic muscle groups.
D) All of the above.
