Answer - C - The total bandwidth for a PCI slot that incorporates a 64-bit PCI bus operating at a clock speed of 66MHz is 528 MBps.

Key Takeaway: This PCI standard operates at a clock speed of 66 MHz and uses 64 bits. The total bandwidth is given by clock speed * byte length. This equals 66 MHz * 8 bytes. Hence, the total bandwidth is 528 MBps.
