To 'Pan' in 3D modelling. Do you move the direction of the camera, or the camera itself?

We currently have some coursework at uni using OpenGL. Part of the coursework is to implement a 'pan' feature. However there is some confusion as to what 'panning' actually involves when speaking in terms of 3d modelling.

Is it;

A: Keeping the 'eyepoint'/'camera' in the same position, but changing the position it is looking towards. Much like 'panning' in photography when taking a panoramic shot.

B: Keeping the direction of the camera on the same axis, but moving the position of the 'eyepoint'/'camera' in free space perpendicular to the direction it is 'looking'

"Pan" means to move the position of the camera without altering the pitch, roll or yaw, and to maintain the same distance from your subject - no "zooming".
