In diagnosing disc displacement with reduction, all of the following must be present EXCEPT:

A. Reproducible joint noise that occurs at variable positions during opening and closing mandibular movements.
B. Soft tissue imaging revealing displaced disc that improves its position during jaw opening, and hard tissue imaging showing an absence of extensive degenerative bone changes.
C. Soft tissue imaging revealing displaced disc that does not improve its position during jaw opening.
D. May be accompanied by pain, and deviation during movement coinciding with a click.
