2. As shown in Figure 1, in $\triangle A B C$, $A C=$ $B C, \angle A C B=90^{\circ}, A D$ bisects $\angle B A C, B E \perp$ $A D$ intersects the extension of $A C$ at point $F$, and the foot of the perpendicular is $E$. Then the conclusions:
(1) $A D=B F$,
(2) $C F=C D$,
(3) $A C+C D=A B$,
(4) $B E=C F$,
(5) $B F=2 B E$,

Among the correct conclusions, the number is ( ).
(A) 1
(B) 2
(C) 3
(D) 4
2.D.

From $\triangle A C D \cong \triangle B C F$, $A D$ bisects $\angle B A C$, and $A D \perp B E$, we get (1)(2)(3)(5) correct.
