Which of the following is the hypotenuse of the triangle shown?

A right triangle $\triangle ABC$△ABC has its right angle located at vertex $A$A as indicated by a corner square symbol. The triangle is oriented such that vertex $A$A is at the top-right, vertex $B$B is at the top-left, and vertex $C$C is at the bottom right. Sides $interval(AB)$interval(AB) and $interval(AC)$interval(AC) are perpendicular to each other. Side $interval(BC)$interval(BC) is opposite to vertex $A$A.
