Very tricky one… It almost seems like answers A, B and C could be correct. I would actually say it resides on the Symmetrix VCM device (option B):
The Symmetrix Volume Configuration Management (VCM) database stores access configurations that are used to grant host access to logical devices in a Symmetrix storage array. The VCM database resides on a special system resource logical device, referred to as the VCMDB device, on each Symmetrix storage array.

It also depends on engunity. With 5785 code each FA directory got it’s own vcmdb.
