C. A splitter cable can be used to provide power to all PDU cables.
D. The installation cannot proceed until two power feeds are available per PDU.

Answer: D

Explanation:
In order for an Exadata X9M-2 Elastic Rack to be installed, two power feeds are required for each of the three-phase 24kVA PDUs. A single cable from each PDU will not be enough to power the rack, and neither a splitter cable nor rearrangement of the power cables from the servers to the PDUs will be able to provide sufficient power for the system. Therefore, the installation cannot proceed until two power feeds are available per PDU.
