Soreness of the edentulous ridge is often a significant indicator of mechanical and functional issues related to dentures. The correct choice points to excessive vertical dimension. When the vertical dimension of occlusion is too high, it can result in undue stress and pressure on the residual alveolar ridge, leading to soreness. This condition occurs due to the lack of adequate tissue support, causing discomfort during functional activities such as chewing or speaking.

In contrast, while infection at the implant site can cause soreness, it is typically accompanied by other symptoms such as inflammation and pus or discharge, which would not solely indicate issues with the edentulous ridge itself. An improper denture fit could also lead to soreness, but it is more about the fit and alignment rather than the actual vertical dimension of occlusion. Bone resorption is a process that can affect the ridge over time, but it would not directly cause immediate soreness unless it significantly altered the ridge's anatomy or led to improper denture fit. Thus, excessive vertical dimension is a straightforward and common reason for soreness in the edentulous ridge, making it the most applicable answer.
