Free Body Diagrams: Representing a Pin Support Correctly

When drawing the FBD of a 2D beam with a pin support at A, which correctly represents the pin reactions?

Select your answer

ATwo reaction components

A_x

and

A_y

acting on the beam

BA single reaction perpendicular to the beam only

CAn unknown moment reaction only

DNo reactions — pins are frictionless so they transmit nothing
