Math Question

Consider the following diagram.
In the above bridge, \( \overline{\mathrm{BD}} \) is the perpendicular bisector of \( \overline{A C} \). For the bridge to be safe, \( \triangle A B D \cong \triangle C B D \). Considering strictly the information that was given, what sequence of reasons can you use to prove that \( \triangle A B D \) and \( \triangle C B D \) are congruent?
(A) \( \angle A \cong \angle C \) (Third Angle Theorem) and \( \triangle A B D \cong \triangle C B D \) (ASA)
(B) \( \overline{A D} \cong \overline{C D}(C P C T C) \) and \( \triangle A B D \cong \triangle C B D \) (SSS)
(C) \( \overline{B D} \cong \overline{B D} \) (Reflexive Property) and \( \triangle A B D \cong \triangle C B D \) (SAS)
(D) \( \angle A D B \cong \angle C D B \) (Corresponding Angles Theorem) and \( \triangle A B D \cong \triangle C B D \) (ASA)
