Denture clicking is typically caused by an excessive vertical dimension of occlusion (VDO), meaning the dentures are too tall, and poor retention, meaning they do not fit securely in the mouth. Option A is incorrect because improper tooth alignment alone is not a common cause of denture clicking. Option C is incorrect because insufficient VDO does not typically cause denture clicking. Option D is incorrect because while poor base adaptation may contribute to denture clicking, it is not listed as a likely cause, and improper tooth alignment is already included in option A.
